The distance covered by the car in the time interval is. Find the acceleration and time taken by the car to cover this distance. Find this acceleration and the distance travelled by car in 10s. It then runs at a constant velocity an dis finally brought to rest in 64 m with a constant retardation. The total distance covered by the car is m Find the value of acceleration, retardation, and total time taken. The acceleration of the car is:.

Before studying motion in a resisting medium, a brief review of uniformly accelerating motion might be in order. That is, motion in which the resistance is zero. Any formulas that we develop for motion in a resisting medium must go to the formulas for uniformly accelerated motion as the resistance approaches zero. One may ask three questions:. Since the acceleration is uniform, there is no need to use calculus to derive these. The first follows immediately from the meaning of acceleration.

Problems on velocity and uniform acceleration are presented along with detailed solutions. Tutorials can also be found in this website. Nothing is said about the initial position and we therefore assume it is equal to 0. Solution to Problem 3: a The acceleration a is a measure if the rate of change of the velocity within a period of time. Solution to Problem 4: a We consider that the direction from ground up is the positive direction of the falling object. The acceleration a of the bicycle is the rate of change of the velocity and is given as follows. What is the position of the object at the end of the 5 seconds of acceleration? To approximate the height of a water well, Martha and John drop a heavy rock into the well. What is the height of the well. Solution to Problem a In this problem we have: 1 a rock was dropped down the well and is uniformly accelerated downward due to gravity.
