Part A = 8.075 m/s
Part B = 0.255 m
What is his speed as he lands on the trampoline, 2.2 m below his jump off point?
If the trampoline behaves like a spring with spring stiffness constant 7.1 * 10^4 N/m , how far does he depress it? Any depression of the trampoline from equilibrium is to be taken as a negative distance.
Part A = 0
Part B = equal to
Part C = 500 kg·m/s
What is the momentum PA,i of piece A before the explosion?
During the explosion, is the force of piece A on piece B greater than, less than, or equal to the force of piece B on piece A?
The momentum of piece B is measured to be 500 kg·m/s after the explosion. Find the momentum PA,f of piece A after the explosion.
What must the charge (sign and magnitude) of a particle of mass 1.43 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 660 N/C?
What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude to its weight?
