Mars rotates on its axis once every 1.02 days (almost the same as Earth does). (a) Find the distance from Mars at which a satellite would remain in one spot over the Martian surface. (Use 6.42 1023 kg for the mass of Mars.) m (b) Find the speed of the satellite. m/s
A 9 m, 260-N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.5, and the ladder makes a 50° angle with the ground. How far up the ladder can an 800-N person climb before the ladd..
