1. A cylindrical room is rotating just fast enough so that blocks A and B do not drop. The coefficient of static friction between blocks A and B is 0.50. If block A is located 5 m from the axis of rotation, determine the minimum speed block A must travel so it does not fall down.
2. A cannon ball is fired upward at 45 degrees above the horizontal and rises to a max height of 1000 m. What is the muzzle velocity of the cannon?
3. A block slides down a slope inclined at 37 degrees. If the slope is frictionless, what is the block's acceleration? Apply energy conservation principles and table 2.2 to solve. Additionally, you can use the information obtained in the question regarding the block's velocity to solve.

1 What is the Earth's orbital speed as it orbits the Sun. Take the Earth/Sun distance to be 93 million miles (taking the Earth's orbit to be circular), the mass of the Earth to be 5.97 X 102 kg and the mass of the Sun to be 1.987 X 10*0 kg. Solve this problem using Newton's 2nd law directly 2. A 55.7 kg mass is lifted (at a constant velocity) from the ground to a vertical height of 1275 m....

A mass m = 1 kg slides down a θ = 30◦ inclined plane from a
height of 5 m. At the bottom of the incline, it collides with
another mass M = 3 kg, and the latter is initially at rest as shown
in Fig. 3. The surface to the right of the inclined plane on which
the 3 kg (green) mass sits is horizontal.
(a) The inclined surface is frictionless. Conserve energy to
find the velocity of the...
