Thermodynamics Question

A hot-air balloon achieves its buoyant lift by heating the air inside the balloon, which makes it less dense than the air outside.

its simple physics i'm just to busy to do it

1. A net force of 2000N act on a rocket of mass 1000. kg. How long must the force be applied in order to increase the rockets velocity from 10.0 m/s to 200.0 m/s.

2. Marble A, mass 5.0 g, moves at a speed of 20.0cm/s. It collides with a second marble, B, mass 10.0 g, moving at 10.0cm/s in the same direction. After collision, marble A continues with a speed of 8.0 cm/s in th same direction. (a) calculate the marbles' momenta before the collision 9b0 calculate the speed of marble B after the collision.
