Which of the following are in equilibrium? Choose all that apply. [NOTE: "spinning up" means the rate of spin is increasing. "spinning down" means the rate of spin is decreasing.] A disc that is speeding up and is not rotating. A baseball that is at rest and has a constant angular velocity. A turntable that has a constant velocity and is spinning up. A tire that is speeding up and is spinning up. A wheel that is at rest and...

A disk starts spinning from rest at t=0, with a constant angular acceleration of 1.2 rad/s2. The radius of the disk is 0.4 m. Consider a bug clinging to the outer edge of the disk. What is the magnitude of the acceleration felt by this bug at t=1 s? Choose the closest answer.

a: A car is accelerating uniformly from a rest state at 4 m/s^2. What distance does the car travel for 3 secs? b: Two equal and opposite forces of 3.0 N act on an object. What is the unbalanced force on the object? c: A 2kg ball with a velocity of 3 m/s strikes a 1kg stationary ball and the two balls stick together and move after the collision. With what velocity will the balls move after the collision? d:...

A car starts from rest and accelerates at a constant rate until it reaches 75 mi/hr in a distance of 220 ft, at which time the clutch is disengaged. The car then slows down to a velocity of 25 mi/hr in an additional distance of 570 ft with a deceleration which is proportional to its velocity. Find the time t for the car to travel the 790 ft.

Problem #2 Collar A starts from rest and moves downward with a constant acceleration of 7 ins. Collar B moves upward with a constant acceleration and has an initial velocity of 8 ins. Knowing that collar B moves through 20 inches in the first 2 seconds, determine the following: (a) Accelerations of B and C (b) The time at which velocity of C is zero (c) The distance that C moves in the time determined in part b.
