A particle is projected vertically upward in a constant gravitational field with an initial speed Vo. There is a retarding force proportional to the instantaneous speed. Calculate the time it takes to come back to the initial position.

Estimate the gravitational force acting on you?

Determine the velocity v(t) and position r(t) of a particle of mass m that is projected vertically upwards with initial velocity v, in a uniform gravitational field in a medium with a frictional force proportional to the velocity.

Assuming the earth to be sphere of uniform mass density, how much would a body weight half way down to the centre of the earth, if it weighted 100 N on the surface.

(c) A small object was found to drop above the surface of a big planet with no initial velocity and it fell 13.5 m in 3 s. If the radius of the planet is 5.82 x 10° m, calculate the small object's acceleration during the fall and the mass of the big planet.

Imagine that two identical containers, one filled with marbles and the other filled with Styrofoam beads, are released simultaneously from rest from the same height-s Earth's surface. (a) Which container, if either, experiences the greater gravitational force? O the container filled with marbles O the container filled with beads O Both containers will experience the same gravitational force. Justify your answer. O Since both containers fall to the ground with the same acceleration, both will experience the same gravitational force. O Gravitational force is directly proportional to mass, so the heavier container would experience the greater gravitational force. O Gravitational force is inversely proportional to mass, so the lighter container would experience the greater gravitational force. O Since the acceleration due to gravity is 9.8 m/s² for each container, both will experience the same gravitational force. (b) which container, if either, experiences the greater acceleration from…
