Its acceleration is 5m/s2.
The formula for acceleration is Final speed - initial speed/time.
So 40m/s - 25m/s is 15m/s.
15m/s divided by 3s is 5m/s2.
Thus the acceleration is 5m/s2

Answer:
b) 338 N
Explanation: let m be the mass of the gymnast and a be the acceleration of the gymnast.
the force required to accelerate the gymnast is given by:
F = m×a
= (45.0)×(7.50)
= 337.5 N
Therefore, the force a trampoline has to apply is 138 N.
