Solve Q4 step by step in copy

Answer 1

As the motor boat starts from rest, initial velocity, u = 0 m/s

acceleration, a = 3 m/s²

time taken = 8 seconds

displacement of boat, s = ?

From laws of motion,

→ s = ut + ¹/₂ at²

→ s = ¹/₂ at²

→ s = ¹/₂ (3)(8)²

→ s = ¹/₂ (3)(64)

→ s = ¹/₂ (192)

→ s = 96 m

Thus, the boat travels 96 metres in 8 seconds with an acceleration of 3m/s²

Hope it helps!!
