Kyle, a 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.437 meters off the ground. He hits the ground 0.0307 meters away from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: m/s

A small block with mass 0.200 kg is released from rest at the top of a frictionless incline. The block travels a distance 0.508 m down the incline in 2.00 s. The 0.200 kg block is replaced by a 0.400 kg block. If the 0.400 kg block is released from rest at the top of the incline, how far down the incline does it travel in 2.00 s?
Amswer both parts or none Part A - A ball is thrown straight down with an initial speed of 2.4 m/s from a height of 75 m. What is the position of the ball after 2.6 s, in meters? Use g = 10 m/s2. Part B - Two big bugs, Buzz and Crunchy each of mass 0.60 kg, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 4.3 m and it spins with an angular speed of 90 degrees/second. What is the magnitude of the net force on Crunchy, in Newtons?
A 730 N student stands in the middle of a frozen pond having a radius 5.0 m. She is unable to get to the other side due to a lack of friction between her shoes and the ice. To overcome this difficulty, she throws her 2.6 kg physics textbook horizontally toward the north shore at a speed of 5.0 m/s. How long does it take her to reach the south shore?
A 10-m-long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 40 m/s when a 60 kg skydiver drops out by releasing his grip on the glider. What is the glider's speed just after the skydiver lets go?
Problem B2. A small box of mass m = 1.50 kg starts from rest and glides down a smooth, frictionless hill from a height h = 2.00 m to the base, where it meets a rough plank of mass M = 5.00 kg that is resting on the frictionless horizontal ground surface. Due to the friction between the box and the plank, its speed is reduced until, at a certain moment, it begins to move together with the plank as if they were a single object. M Figure B2. Problem diagram B2 c) Calculate the work done by the friction forces present in the problem.
