Estimate the average pressure exerted on the ground by a red kangaroo when it jumps straight up to a 1.6 m height. Use the following parameters: the kangaroo's mass m - 44.3 kg, the time of the contact between the kangaroo's feet and the ground during the jump t = 0.16 sec, and the kangaroo's foot area A = 29.6 cm². Assume that the kangaroo jumps by pushing with it's both feet. The pressure produced by the jumping kangaroo, P-...

A 9.1-kg child sits in a 3.2-kg high chair. Part A Complete the child's free-body diagram by adding the forces that act on the child. Draw the vectors with their tails at the black dot. The location and orientation of the vectors will be graded. The exact length of the vectors will not be graded but the relative length of one to the other will be graded. Find the normal force exerted by the chair on the child. Express your...
