60 Km/h = 60 × 1000 = 60,000 m/s
Acceleration = Change in velocity / Change in time
so , a = v - u / t
.'. a = 60,000 - 0 / 10
.'. a = 60,000 / 10
.'. a = 6,000 / 1
.'. a = 6,000
Then the Acceleration is 6,000 m/s2 ..........
OR :-
10 seconds = 10'÷ 60 = 1/6 hours
Acceleration = Change in velocity / Change in time
so , a = v - u / t
.'. a = 60 - 0 / (1/6)
.'. a = 60 / (1/6)
.'. a = 60 × 6
.'. a = 360
Then the Acceleration is 360 km/h2 ..........
So the Acceleration is either 6,000 m/s2 or 360 Km/h2

If a rock dropped on the Moon increases speed from 0 m per s to 8.15 m per s in about 5 seconds What would be the gravitational acceleration?
The gravitational acceleration would be the change in velocity divide by the time required. For this example 8.15 m/sec divided by 5 seconds yields 1.63 m/s2. (The actual average lunar gravity is estimated at 1.622 m/sec2.)
What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²?
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
What is the acceleration on a distance time graph measured in?
Acceleration has a dimensionality of length/time^2, so if you were measuring the distance in meters and the time in seconds, the acceleration would be m/s^2.
What is a roller coasters average acceleration if its speed is 4 m s and three seconds later its 22 m s?
The acceleration of the roller coaster would be 88 MPH. This was figured out by doing math.
How do you work out velocity when given acceleration and time?
Answer: v=u + at v (Velocity) = u (Starting velocity) + a (acceleration) x t (time) So, starting from stationary (u=0), the velocity is simply a x t e.g. if the acceleration is 5mph per second per second, after 10 seconds you would be travelling at 50mph. Answer: The above is for constant acceleration. In the case of variable acceleration, integration has to be used.

What is a skydivers velocity after 2 seconds?
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.
How long would it take a car to accelerate from 10 MPH to 75 MPH if its acceleration is 20 MPHs?
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds

What is the velocity of the object 0.10 seconds after it is released?
To answer this question we would need to know the acceleration, which is not provided.
If mass increases and there is no friction would the acceleration of an object increase when place on an incline plane?
Yes. The acceleration is directly proportional to the objects mass.For objects with constant mass however, the acceleration will remain constant.
What would the acceleration be if it took 10 seconds to go from 8ms to 18ms and why?
Divide the difference in speed by the time it takes. This will give you the average acceleration for that time period.
What is the length of simple pendulum when it ticks seconds?
known to be seconds pendulum,the length would be almost 1m when acceleration due to gravity is 9.8m/s2
If you went 0 to 55 mph in 6 seconds what would be your acceleration?
55/6 = 9.16666...mph/s
A motorcyclist is able to ride on the vertical wall of a bowl shape track as shown does?
As the speed increases the centripetal acceleration increases. This this acceleration is caused by the normal force, then the normal force increases. Frictional force however remains equal to the weight. As the normal increases the maximum frictional force would increase. However, the amount of friction needed would still only be the rider's weight. In other words the frictional force would be less than the maximum available frictional force.
Can a body have constant acceleration and zero velocity?
Since the derivative of velocity is acceleration, the answer would be technically 'no'. Here is why: v = 0 v' = 0 = a Or in variable form... v(x) = x v(0) = 0 v'(0) = 0 = a You can "trick" the derivative into saying that v'(x) = 1 = a (since the derivative of x = 1) and then stating v'(0) = 1 = a... but that is not entirely correct. Acceleration is a change over time and is measured at more then one point (i.e. the acceleration of this body of matter is y from time 1 to 5) unless using derivatives to form the equation of the acceleration line/curve. If an object has a constant acceleration of 1, then the velocity is constantly increasing over that time. Using the equation discussed above and looking at acceleration over time, at 0 seconds, acceleration is 0 and so is velocity, but from 0-1 seconds acceleration is 1 and velocity is 1 as well. 0-2 seconds, acceleration is 1, but velocity would be 2 (at the end of 2 seconds).
