A 2.44 x 10^3 kg car requires 5.3 kJ of work to move from rest to some final speed. During this time, the car moves 27.4 m.

Neglecting friction, find

a) the final speed

b) the net horizontal force exerted on the car

We all depend on electricity. Most electricity is created by electromagnetic generators at large power plants and distributed through an electric grid.

Quarks are thought to be the basic component of

A Tesla Roadster car accelerates from rest at a rate of 7 M / s^2 for a time of 3.9 s calculate the distance it travels In time.

Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 18 m/s at an angle 42 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground.
