A small, 10.0 g insect stand at one end of a thin uniform metal rod which is initially at rest on a frictionlesshorizontal table. The other end of the rod is bolted into the table, so that the rod pivots without friction. The rod has a mass of 100.0 g and is 100.0 cm long. The insect jumps in the horizontal direction, perpendicular to the rod, with aspeed of 40.0 cm/s relative to the table.
(i) What is the resulting angular speed of the rod?
(ii) What is the total kinetic energy of the entire system after the bug leaps?

A ranger in a national park is driving at 59 km/h while a deer jumps onto the road 61 m ahead of the vehicle. After a reaction time of t s, ranger applies the brakes to produce an acceleration of -3 m/s2. What is the maximum reaction time allowed if ..
What will be the resulting speed of the boat. A 74 kg fireman slides down a 4-m pole by applying a frictional force of 384 N against the pole with his hands. If he slides from rest, how fast is he moving once he reaches ground.
A 0.27 kg rock is thrown perpendicularly upward from the top of the cliff that is 32 m high. When it hits the ground at the base of cliff, the rock has a speed of 29 m/s. suppose that air resistance can be ignored, find out A) initial speed of the ro..
A spring with 49 N/m hangs vertically next to a ruler. The end of the spring is next to the 17-{rm cm} mark on the ruler. If a 2.0-{rm kg} mass is now attached to the end of spring, where will the end of the spring line up with the ruler marks.
