Answer 1

QUESTION ---- Calculate the acceleration of a body which starts from rest and travels 87.5 m 5 seconds

ANSWER
____________________________

Distance (s) = 87.5
Time (t) = 5 Seconds
Initial velocity (u) = 0
Acceleration (a) = ???

Using Second Equation of Motion,

s = ut + 1/2 at^2

ut will be equal to zero because u = 0

87.5 = 1/2 × a × 5 × 5

87.5 = 1/2 × 25a

87.5 = 25/2 a

=> a = 87.5 × 2 /25

=> a = 175 / 25

=> a = 7 m/sec ^2
______________________________

ANSWER = ACCELERATION = 7 m/sec ^2
