After falling from rest from a height of 33 m, a 0.55-kg ball rebounds upward, reaching a height of 23 m. If the contact between ball and ground lasted 2.1 ms, what average force was exerted on the ball?
A proton is projected in the positive x direction into a region of uniform electric field = (-6.80 105) N/C at t = 0. The proton travels 6.70 cm as it comes to rest. (a) Determine the acceleration of the proton.
An electron is accelerated through 2450 V from rest and then enters a region where there is a uniform 1.20 T magnetic field. What are the maximum and minimum magnitudes of the magnetic force acting on this electron?
A beam of 5 MeV electrons passes through a 300 micro-m silicon detector. Estimate the energy lost by the electrons when crossing 100 micro-m, 200 micro-m, and the full thickness of the detector.
The coefficient of kinetic friction is 0.20. A horizontal force of magnitude 57 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?
At what horizontal distance, x, from the base of the building will the rock strike the ground? Assume the ground is level and that the side of the building is vertical. The acceleration of gravity is 9.8 m/s2.
