A boat has a mass of 6800 kg. Its engines generate a drive force of 4300 N, due west, while the wind exerts a force of 910 N, due east, and the water exerts a resistive force of 1200 N due east. What is the magnitude and direction of the boat's acceleration?

4300N - 910N - 1200N = 2190N west
one newton is 1 kg * m/s/s, so
2190N / 6800 kg = 0.322 m/s/s west

the respond is B. in the previous the collision, you're traveling in a at contemporary line, with the vehicle pushing you forward. for the time of the turn, your physique tries to maintain its forward momentum, yet you're contacted by using the vehicle door by way of fact the vehicle moved for the time of the turn. The door (collision) then exerts a leftward rigidity on you, inflicting you to bypass in that direction with the vehicle. it is declared as centripetal rigidity.
