Question

A particle has initial velocity 10 m/s. It moves due to constant retarding force along the line of velocity which produces a retardation of 5 m/s2. Then

  1. the maximum displacement in the direction of initial velocity is 10 m    
  2. the distance travelled in first 3 seconds is 7.5 m    
  3. the distance travelled in first 3 seconds is 12.5 m    
  4. the distance travelled in first 3 seconds is 17.5 m    

The correct answer is: the maximum displacement in the direction of initial velocity is 10 m
