1500 kg car increases its speed by 2 m/s for each second of travel. what is the net force acting on the car?

You have said that the car's mass is 1,500 kg, and its acceleration is 2 m/s² .

This information leads directly to the net force on the car,
by way of Newton's 2nd law of motion:

       Force = (mass) x (acceleration)

       Force = (1,500 kg) x (2 m/s²) = 3,000 kg-m/s² = 3,000 newtons

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

M= 2250 kg & v = 32km / h = 8.8m/s, t = 4s. so, a = 8.8 / 4 = 2.2 f = ma = 2250 * 2.2 = 4950 n~ hope this (may i have brainy if this is
