A group of students conduct the ballistic pendulum experiment, the same one we will do. The mass of their projectile was 70 grams, the mass of the block/pendulum was 250 grams. The true/effective length of the pendulum was 35 cm. The experiment was done on Earth where the local acceleration due to gravity is 9.80 m/s2. The pendulum swung up to a 38° angle. What was the speed of the projectile out of the cannon before it collides with the...

Consider a satellite of mass m in a circular orbit of radius r around the Earth of mass ME and radius RE. 1. What is the gravitational force (magnitude and direction) on the satellite from Earth? 2. If we define g(r) to be the force of gravity on a mass m at a radial distance r from the center of the Earth, divided by the mass m, then evaluate the ratio g(r)/g(RE)to see how g varies with radial distance.

In the  23rd century, an Earth probe to the planet Altair IV (mass 1.05x1024 kg, radius 3.68x106 m) has a communications failure. To request assistance, a small projectile is shot toward Earth from the surface of the planet, at speed 17.5x103 m/s (which is greater than the escape speed). Ignore friction and all other objects in the universe, and assume the projectile has no fuel. Find the speed of the projectile, in m/s,when it reaches Earth, which is far enough from...
