1.what is the diffference blw linear accelerated motion and falling body.2 A 1500g car starts from rest and increase it velocity to 30 per second in a time of 25 sec. calculate the acceleration of the car. calculate the distance the car travel. How much force was used. How much force was done.​

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.

Ithink it’s b hope it
