- You go where no one has gone before and discover an interesting planet of radius r. When you arrive, you clearly want to do some experiments to learn more about this world. You begin with some simple kinematics and measure the time t for an object thrown directly up with velocity vi to return to your hand. With this information, you find that the acceleration due to gravity gi s much lower than on Earth. a) You decide to orbit the planet in your spacecraft at a distance Rabove the surface of the planet. Find the time required to complete one orbit in terms of R, r, vi, t, and any necessary constants. b) FInd the escape velocity ve–the initial velocity necessary for an object to barely escape the gravitational pull of the planet. Express your answer in terms of vi, r, t,and any necessary constants. c) Find the distance from the planet’s center at which an object launched from the surface with velocity vwill have lost 90% of its initial kinetic energy at the surface in terms of v,vi, r,…n vx dug have Ar vx rack обока 1. Conceptual Question! A 15kg rock is thrown horizontally at the same time that a 5g ball is dropped from rest, from the same height as the ball. Their trajectories are shown in figure 1: Point A is the release point for both objects; at point B, both objects have been traveling the same amount of time from the time of release; at point C, both objects are just about to hit the ground.

At the bottom of its arc, a rider in one swing is moving at 30 m/s with respect to the ground in a 50-m-diameter circle. The rider in the other swing is moving in a similarcircle at the same speed, but in the exact opposite direction.a. What is the acceleration, in m/s2 and in units of g, that riders experience?b. At the bottom of the ride, as they pass each other, how fast do the riders move with respect to each other?

The stream is 6 m wide and the east bank of the stream is 1m higher than the west bank (where the bear starts). The bear can jump with an initial velocity vi (4m/s, 4m/s) , and decides to start from 3m in the air, halfway up a sturdy tree. Part 1 If the origin is at the bear's foot (up in the tree), write an equation describing the coordinate of the bear while it is in the air. Use the following table as a reference. Note that it may not be necessary to use every variable. For Use Δt t g gA ball is suspended from a light 1.3 m string . The string makes an angle of 24 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1m/s. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? What will be the maximum angle, in degrees, the string will make with the vertical?
