Question

A boat has a mass of 5390 kg. Its engines generate a drive force of 3660 N due west, while the wind exerts a force of 910 N due east and the water exerts a resistive force of 1520 N due east. Take west to be the positive direction. What is the boat's acceleration, with correct sign? A boat has a mass of 5390 kg. Its engines generate a drive force of 3660 N due west, while the wind exerts a force of 910 N due east and the water exerts a resistive force of 1520 N due east. Take west to be the positive direction. What is the boat's acceleration, with correct sign?

Explanation / Answer

Resistive forces F = 3660 - 910 - 1520 = 1230 N

F = m a

a = F / m = 1230 / 5390

Boat's acceleration = 0.228 m/s2
