Consider a stationary object placed at rest on a horizontal table. A firecracker explodes inside it and two unequal parts of the original object fly away in opposite directions. If the mass of the lighter chunk is mA and that of the heavier chunk is mB = 5mA, what is the ratio of their kinetic energies (KB/KA) after the explosion?

A 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0.00 s, the block has a displacement of a velocity of and an acceleration of The force constant (spring constant) of the spring is closest to

A 6.52 gram bullet is fired into a 0.601 kg block attached to the end of a 0.670 m non uniform rod of mass 0.698 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about A is 0.0550 kg m2. If the angular speed of the system about A just after impact is 1.96 rad/s, what is the bullet’s speed (in m/s) just before the impact? Treat the block as a particle.

Astronaut Jennifer’s lifeline to her spaceship comes loose and she finds herself stranded, “floating” 100 m from the mothership. She suddenly throws her 2.00-kg wrench at 20 m/s in a direction away from the ship. If she and her spacesuit have a combined mass of 200 kg, how long does it take her to coast back to her spaceship?
