Answer:
Time taken, t = 5 seconds
Displacement, s = 5 metres
Initial velocity, u = 0 metres/second
Let the acceleration be a m/s2m/s2.
When the acceleration is constant, initial velocity, acceleration, time taken and displacement are related by a simple formula:
s=ut+(1/2)at2s=ut+(1/2)at2
Therefore,
5=(0)(5)+(1/2)(a)(52)5=(0)(5)+(1/2)(a)(52)
a×(25/2)=5a×(25/2)=5
a=5/(25/2)a=5/(25/2)
a=10/25a=10/25
a=2/5
a=0•4
