After a day of testing race cars, you decide to take your own 1478 kilogram car onto the test track. While moving down the track at 11.7 m/s, you suddenly accelerate to 28.8 m/s in 12.6 second. Find what average net force has you applied to the car during that time?
Answer in units of N
A wedding ring (of diameter 1.7 cm) is tossed into the air and given a spin, resulting in an angular velocity of 12 rotations per second. The rotation axis is a diameter of the ring. Taking the magnitude of the Earth's magnetic field to be 4.3 10-5 T..
