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!!
