Current Attempt in Progress A 54.0-kg person, standing on a diving board, dives straight down into the water. Just before striking the water, her speed is 4.75 m/s. At a time of 1.77 s after entering the water, her speed is reduced to 1.34 m/s. What is the magnitude of the average net force that acts on her when she is in the water? Vo Number i Units

A 16.2 kg box (labelled m1) rests on a table. Weight of box is 160N, and the normal force acting on it from the table is 160N. A second box m2, of mass 1.93 kg, is placed on top of the 16.2 kg box. 1. Determine the normal force (in newtons) that the table now exerts on the 16.2 kg box. 2. Determine the normal force (in newtons) that the 16.2 kg box exerts on the 1.93 kg box.

Blocks A, B, and C are being pushed across a frictionless table by a constant horizontal force F = 12 N. Block A has mass 2M, block B has mass 3M and block C has mass M. The blocks move to the right. 1) what's the contact force between B and C? 2) what's the contact force between A and B?

A teenager of mass m1 = 56 kg pushes backwards against the ground with his foot as he rides his skateboard. This exerts a horizontal force of magnitude F foot = = 18.5 N. The skateboard has m2 = 2.6 kg. a. Write an expression for the magnitude of the horizontal component of force that the ground exerts on the teenagers foot, F ground. b. Write an expression in terms to given quantities for the magnitude of the skateboard acceleration, a , while the teenager is pushing backwards on the ground? c. What is the numerical value of the magnitude of the acceleration, a, in m/s square?

A boy standing on a frictionless wooden deck pulls two large wooden blocks that are held together by a rope. From the horizontal with an angle theta, F( F with a vector sign) is the pulling force and the two blocks accelerate. Considering the rope is not able to extend more and doesn't have a mass, a) Sketch the free body diagram if the mass of one block is m1 and the other is m2. b) In relation to F, theta, m1 and m2; determine the magnitude of the tension next to the rope that is connecting the two blocks. c) F = 30N, theta = 35 degrees, m1= 6. 5kg and m2 = 4.8kg, find the magnitude of tension.
