A simple word problem on finding acceleration of a body at uniform motion. Problem is all about acceleration and velocity of body.
Topic : Acceleration of a Body at uniform motion
Rate of change of velocity is called as acceleration, here is one example for how to find acceleration.
Question : What is the magnitude of the average acceleration of a skier, who starting from rest, reaches a speed of 8 m/s while going for 5 s. Also, how far does he travel?
Solution :
Average acceleration is the rate at which velocity changes. Average acceleration is the change in velocity divided by an elapsed time.
V initial =0m/s, at t=0 s
V final=8m/s, at t=5 s
Average acceleration=change in velocity/change in time
Average acceleration= V final- V initial/T final- T initial
= (8-0)/(5-0) =8/5 =1.6 m/sec2
