You throw a ball vertically upward so that it leaves the ground with velocity 6.05 m/s. (a) What is its velocity and direction when it reaches its maximum altitude? magnitude m/s (b) What is its acceleration and direction at this point? magnitude m/s^2 (c) What is the velocity and direction with which it returns to ground level? magnitude m/s (d) What is its acceleration and direction at this point? magnitude m/s^2
A simple pendulum has a mass of 0.350 kg and a length of 7.00 m. It is displaced through an angle of 12.0° and then released. Solve this problem by using the simple harmonic motion model for the motion of the pendulum.
If the spring stretches by 2.4cm, what is the coefficient of static friction between the backpack and the table.
The jet accelerates uniformly, and during that time, the pendulum oscillates about the equilibrium position shown by the solid line, with D = 0.370 m. find the magnitude of the plane's acceleration.
Billy has a bucket that has a mass of 150 g, in which he put 150 g of fresh water. He has tied 150-cm of string to the handle of the bucket.
For a damped oscillator with a mass of 180 g, a spring constant 58 N/m and a damping coefficient of 60g/s, what is the ratio of the amplitude of damped oscillations to the initial amplitude at the end of 26 cycles.
