3. Suppose that a 1000 kg car is traveling at 18 m/s. Its brakes can apply a force of 4000 N. What is the minimum distance required for the car to stop? (Hint: first find acceleration and then use kinematic equation to find the displacement.) 4. Find the time required for the car in question-3 to stop.

Rubber on floor tile has a coefficient of kinetic friction of 1.0 and a coefficient of static friction of 2.0. how much force would a 3.5 lb. robot need to produce in order to start moving?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
