Compute:
a. The velocity of an object orbiting at a distance of 4.5 x 107 m from the center of a
spherical object whose mass is 3.0 x 1023 kg.
b. Compute the orbital period of that object.

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

Acar is traveling 35 mph on a smooth surface . if a balanced force is applied to the car what happens?
