A 60 kg skydiver is falling at a constant speed near the surface of Earth. The net force on the skydiver is

A car is rounding a turn on a road that is banked at some angle with respect to the horizontal. The road is covered with ice and there is no friction between the road and the tires. which of the following forces is responsible for keeping the car on its circular path? The horizontal component of the force of gravity It is impossible for the car to stay on a circular path in this situation The vertical component of the force of gravity The horizontal component of the normal force The vertical component of the normal force Complete the following sentence. Centripetal forces enable objects to follow circular trajectories with constant speed. enable objects to follow circular trajectories with constant acceleration. O are described by Hooke's law for springs. double in magnitude when an object's speed in uniform circular motion is doubled. OOOO

A spacecraft flying horizontally over the surface of the moon at an elevation of 1500m with a speed of 350m/s, drops a package with a mass of 1200kg to astronauts on the surface. Use gm= 1.6m/s2 for the acceleration due to gravity on the Moon. a)How long does it take the package to hit the surface after it is dropped? b)How far ahead (distance) of the package’s landing spot should the package be released? c)What is the velocity of the package just before it hits the surface? d)What is the magnitude of the velocity of the package just before it hits the surface of the Moon?

Suppose the mass of a fully loaded module in which astronauts take off from the Moon is 12,200 kg. The thrust of its engines is 27,000 N. (Assume that the gravitational acceleration on the Moon is 1.67 m/s².) (a) Calculate (in m/s²) its magnitude of acceleration in a vertical takeoff from the Moon. m/s² (b) Could it lift off from Earth? If not, why not? Yes, the thrust of the module's engines is equal to its weight on Earth. ◇ No, the thrust of the module's engines is equal to its weight on Earth. No, the thrust of the module's engines is less than its weight on Earth. Yes, the thrust of the module's engines is greater than its weight on Earth. If it could, calculate (in m/s²) the magnitude of its acceleration. (If not, enter NONE.) m/s²
