Acar has a mass of 1100 kg. by pushing on the car, evan increases its speed from 2 m/s to 3 m/s. what impulse did evan apply to the car?

He had to push an extra of 1100 to get it to 3300 so the answer is 1100 kgm/s.

Ithink it’s: light bounce if off a mirror

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.
