If A car travels down the highway at 55 mph its speed is what and its acceleration is what?
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
What is the velocity of an object that travels 15 meters in 2 seconds?
7.5
What is the average velocity of an object that travels 6 meters north in 2 seconds and then travels 3 meters east in 1 second?
3.00 m/s
What is the deceleration of a bicycle that travels from a velocity of 12meters per seconds in 2s?
Calculation of deceleration the speeds at two points in time.
Find is the velocity in miles per hour of a mass that travels 50 feet in 20 seconds?
1.7 miles per hour.
What is a cars acceleration if it travels 0 to 55 miles per hour in 6 seconds?
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
A train travels from one city to another its initial velocity is lower then its final velocity?
Positive acceleration.
If an object travels for 15 minutes at a constant velocity of 12 miles per hour west what is its acceleration?
Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.
What is the acceleration of a car that travels in a straight line at a constant speed of 110 km h?
The acceleration of an object that travels in a constant straight line velocity is zero.
When can you say that there is acceleration?
when the body travels in unequal velocity in equal intervals of time.
If A car travels down the highway at 55 mph its speed is what and its acceleration is what?
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
A car travels 30 m in 5 sec after accelerating for 3 seconds it travels 20 m in 2 seconds Calulate the cars acceleration?
First you need to find the two different speeds of the car which is the distance/time. We find that the car first travels at an average of 6ms-1 and then after accelerating has a speed of 10ms-1. Acceleration is the rate of change of velocity over time, our change of velocity being 10-6=4ms-1 and the change in time being stated as 3 seconds we can convert this into... (4/3)ms-2
What is the velocity of an object that travels 15 meters in 2 seconds?
7.5
What is the velocity of car if travels 40km per hour?
666.67 seconds
What is the acceleration and magnitude of 32.5 kg object that travels 100m in 10 seconds?
You can't calculate the acceleration from the information provided. The object may be traveling at constant velocity, in which case the acceleration is zero; or it may start slowly end end up faster, or vice versa, in which case the acceleration will be non-zero.
What is the acceleration of a car that travels in a straight line at a constant speed of 80 km per hour?
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
Is the distance an object travels in one unit of time called acceleration?
No, the distance an object travels in unit time is called speed. The distance travelled per unit time in a specified direction is called velocity. The rate of change of velocity is called acceleration.
