A 4 kg box is raised from rest adistance of 6 m by a vertical force of110 N.
(a) Find the work done by the force.
(b) Find the work done by gravity.
(c) Find the final kinetic energy of the box.
A spring with a force constant of 585 N/m is compressed a distance of 40 cm. Find the resulting increase in the spring's mass in kg
A cannon of mass 5.17 x 10 3 kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 74.3-kg shell horizontally with an initial velocity of 542 m/s. Suppose the cannon is then unbolted from the earth, and..
An 52.0 N box of clothes is pulled 6.7 m up a 30.0° ramp by a force of 107 N that points along the ramp. If the coefficient of kinetic friction between the box and the ramp is 0.22, compute the change in the box's kinetic energy.
Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.56 m radius and is 1.8 m high. The walls are 1.0 cm thick.
