Q1. A planet of mass 4.00 1025 kg is in a circular orbit of radius 3.00 1011 m around a star. The star exerts a force on the planet of constant magnitude 2.08 1023 N. The speed of the planet is 3.95 104 m/s. What is the magnitude of change in momentum of the planet?

Q2. A block of mass 4.0 kg is put on top of a block of mass M = 5.5 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 16 N must be applied to the top block. The assembly of blocks is now placed on a horizontal, frictionless table.

(a) Find magnitude of the maximum horizontal force F that can be applied to the lower block so that the blocks will move together.

(b) Find magnitude of the resulting acceleration of the blocks.
