What is the acceleration of an object that starts stopped and after 5 seconds is going 25mm per hour?

the acceleration is increasing speed
Acceleration = velocity change / time
velocity change = 0 to 25 mm/hr = 25 mm/hr
time = 5 seconds
therefore acceleration = 25/5 mm/hr per second = 5 mm per hour per second.

A driver starts his parked car and within 5 seconds reaches a velocity of 54 km per hour as he travels east what is his acceleration?
vf=54 km/hr vi=0km/hr t=5sec/0.001hr a=5400 km/hr 54km/hr- 0km/hr --------------------- 0.001 hr
A baseball is hit straight up at an initial velocity of 100MS How long will it take to hit the ground?
Take acceleration of gravity = 9.8 m/s2 .The ball stops rising and starts falling in (100/9.8) seconds.It returns to the height of the bat in 2 x (100/9.8) = 20.408 seconds. (rounded)
What is the greatest length of time measured on a stopwatch?
There is no upper limit; when the stopwatch reaches the largest number of seconds it can count, it simply starts over. It is your job to count the number of times it starts over. Most digital stopwatches can time up to 20 hours, resetting after 19:59:59.99.
What are false starts?
False starts in 100 metre sprints are when an athlete leaves the starting blocks 0.10 seconds after the gun goes off; the IAAF did tests that show the human brain can't process the information from the sound of the gun in under that time. This precise measuring is only used in higher level tournaments.
How many seconds are in a school week?
A school week consists of the days Monday through Friday. So one answer would be to count every second starting from very second you start school up until you reach the very last second you are in school. Assuming school starts Monday morning at 7:00 AM and ends Friday afternoon at 2:40 PM, then the number of seconds equates to: 24 hours/day * 4 + 6.667 hours/Friday * 1 = 102.667 hours 102.667 hours * 3600 seconds/hour = 369601.2 seconds
What is speed of object at 3 seconds given an acceleration of 16 feet per second squared for 3 seconds?
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
What is the velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
A car starts from rest and reaches 20 ms in 10 seconds The average acceleration of the car in ms2 is?
10
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
If a car starts from rest and travels a distance of 100 meters in 10 seconds what is the car acceleration?
2.0 m/s^2
What is the acceleration of a body which starts from rest and travels 87.5 m in 5 seconds?
distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s
Theory about uniformly accelerated motion?
From a kinematic perspective, just observing the motion of an object, we can say that an object is experiencing uniform acceleration if the magnitude of the object's velocity changes at a constant rate but maintains the same direction. From a dynamic perspective, as a consequence of Newton's second law, we know that whenever the net force on an object is constant (in magnitude and direction) the object will undergo uniform acceleration.
What is a real life example of acceleration?
You have acceleration any time a velocity changes - like when an object falls down due to gravity, when a car starts or stops, when you start moving or stop moving, etc.
The rate of change of an objects position is?
Acceleration occurs when the velocity of an object changes. Velocity is the speed and direction of an object. Newton's Second Law of Motion defines what happens when a force acts on an object. The object accelerates in the direction in which the force is acting. A force acting on a stationery object starts it moving. A force acting on a moving object will speed it up, slow it down, or change the direction in which it is movingDefinition of deceleration: (physics) a rate of decrease in velocityDefinition of acceleration: (physics) a rate of increase of velocityProps to Google :)
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Can an object reverse its direction while maintaining a constant acceleration?
One answer to this is that all object are in motion all of the time relative to all other objects. With that said, in the context of permanent halt" the only way that an object can be perceived as "halted" is by another object with the same velocity.
