Question

25. A motorboat starting from
rest on a lake accelerates in a
straight line at a constant rate
10m/s^2 for 5s. How far does
the boat travel during this
time?
O A) 25 m
O B) 75 m
O C) 105 m
O D) 125 m​

Answer 1

initial velocity = 0 m/s

acceleration = 10 m/s²

time = 5 s

Equation to be used ==> s = ut + 1/2 at²

s = (0×5) + (1/2×10×5×5)

s = 0 + 125

s = 125 m

Therefore, the distance covered by the motorboat is 125 metres.

Your answer is option 'd' which is 125 metres
