1. a 1000-kg car moves as speed from 10 m/s to 30 m/s in 20 seconds. what is the average speed? what is the acceleration? what is the average force acting upon it? if the car turns along a circle at speed 5 m/s around a curve 30 meters in radius, how big the centripetal force is needed?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
