Question

A particle moving with an initial velocity 2.5 m/s along the positive x direction accelerates uniformly at the rate 0.50 m/s² . (i) Find the distance travelled in the first 2 sec. (ii) Calculate the time taken to reach the velocity of 7.5 m/s? (iii) Calculate the distance travelled in reaching the velocity 7.5 m/s?

Answer 1

 This is the case of motion with uniform acceleration. Use the three equations of motion with uniform acceleration.

Since the particle does not turn back it is also the distance travelled.
