88. What is the gravitational potential energy of the container in the lifted position?

3. A piece of shattered glass falls from the 82nd floor of a building. 600 feet above the ground. What is the velocity of the glass when it hits the ground, if air resistance is disregarded? do not use v = square root 2 gh. use the full conversion of mechanical energy equation containing hi and hf And state the reference level used to determine hi and hf.

1. Some species of whales can dive to depths of 800m. What is the total pressure they experience at this depth? (The density of sea water = 1020 kg/m, and 1 ATM =10$ N/m) A 15.0-kg object is pulled along a horizontal surface at a constant speed by a 25 N force acting at 30° above the horizontal. How much work is done by this force as the object moves 10.0 m? A force of F = 3i + 0.5j – 5k), N is applied to a particle located at r = 2i +4k, m. Determine a) The torque vector; b) The angle between the vectors F and r 3. 4. A ball of mass Mi = 0.250 kg and velocity Voi = +5.00 m/s collides head-on with a ball of mass M2 = 0.800 kg initially at rest. No external forces act on the balls. If the collision is perfectly inelastic, find the velocity of mi after collision? Voi M1 M2 2.
