What is the magnitude of the net force acting on a 2.0 x10^3 kilogram car?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
