The motor of a 1780 kg speed
boat pushes 3880 n to the right.
air resistance pushes 512 n to the
left, and the water drags the boat
1910 n to the left. what is the
acceleration of the boat?
(unit = m/s2)

0.82 ms⁻²

Explanation:

consider the way the forces are acting on the boat , in the graph

assume the boat is accelerating to the right

we can apply Newton's second law of motion (F = ma )

→ F = ma

3880 -1910 -512 = 1780 * a

a = 0.82 ms⁻²

acceleration =  0.82 ms⁻²

answer: the answer is a
