    15 seconds
  • b)
    25 seconds
  • c)
    20 seconds
  • d)
    35 seconds
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A body initially at rest moves with a constant acceleration of 15 m/s...
Using the distance-time equation for a body moving with constant acceleration, S = ut +1/2at2 where, S = distance travelled, u= initial velocity, a=acceleration, t= time taken for the body to travel distance s.
Since, the body was initially at rest, u= 0 m/s,
Hence, Putting the values in the equation, S = ut +1/2at2
3000 = 0 + ½ (15 x t2)
Or, t = 20 seconds
