In the figure here, a cylinder having a mass of 3.7 kg can
rotate about its central axis through point O. Forces are applied
as shown: F1 = 8.4 N, F2 = 6.4 N, F3 = 6.6 N, and F4 = 5.6 N. Also,
r = 7.9 cm and R = 18 cm. Ta?king the clockwise direction to be
negative, find the angular acceleration of the cylinder. (During
the rotation, the forces maintain their same angles relative to the
cylinder.)...

A robotic rover on Mars finds a spherical rock with a diameter of 9 centimeters [cm]. The rover picks up the rock and lifts it 15 centimeters [cm] straight up. The resulting potential energy of the rock relative to the surface is 3 joules [J]. Gravitational acceleration on Mars is 3.7 meters per second squared [m/s2]. What is the specific gravity of the rock?

A baseball has a mass of 0.15 kg and radius 3.7 cm. In a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 30 rad/s and a linear speed of 39 m/s. Assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball in joules.

A car of mass 2400 kg collides with a truck of mass 4500 kg at the intersection of horizontal roads. The vehicles stick together and slide immediately after the collision. The x- and y-components of the car’s velocity just before the collision are (36, 0) m/s, respectively, and the same components of the truck’s velocity just before the collision are (-15, 25) m/s. a. calculate the x component of the velocity of the combined car and truck immediately after the...

The figure shows a communications satellite that is a solid
cylinder with mass 1430 kg, diameter 1.24 m, and length 1.64 m.
Prior to launch from the shuttle cargo bay, the satellite is set
spinning at 1.37 rev/s about its long axis. What are
(a) its rotational inertia about the rotation axis
and (b) its rotational kinetic energy?

A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...
