Asimple model shows how drawing a bow across a violin string causes the string to vibrate. as the bow moves across the string, static friction between the bow and the string pulls the string along with the bow. at some point, the tension pulling the string back exceeds the maximum static friction force and the string snaps back. this process repeats cyclically, causing the string's vibration. assume the tension in a 0.33-m-long violin string is 65 n, and the coefficient of static friction between the bow and the string is μs = 0.80. if the normal force of the bow on the string is 0.75 n, how far can the string be pulled before it slips if the string is bowed at its center?

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)
