A gymnast is swinging around a high bar with an initial angular velocity of 2.06 rad/s. He wishes to stop his angular motion in 0.7s. What angular
acceleration must he achieve in this time to come to rest in rad/s^2)?

The velocity of car is 80.0 miles per hour. what is the velocity of car in meters per second? (1 km -0.621 miles) m/s

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
