a 50-kg stunt diver is falling at a speed of 20 m/s. when she is stopped by sinking into a cushion that exerts an average force of 500 n on her. how much time did it take her to stop moving once she hit the cushion?

Abanked road comer of radius 146 m is to be constructed. if the comer is designed for vehicles moving with a speed of 20.0 m/s, what should the banking angle be, in units of degrees?
