A ball of mass m moves along a track in the shape of vertical circular loop. There are 2forces acting on the ball -- the normal force exerted by track (Ntrack) and gravity (mg).Ignore friction and air resistance.The vectors v (velocity) and a (total acceleration) have an angle ◊ between them, whichchanges as the ball moves.Check all the answers which are true statements. There may be more than one correctanswer!when the ball is on the way up the loop, 0 > 90°ºthe magnitude of a is always smaller than g, no matter how fast the ball moves0 = 90° at the "side" points (halfway up the loop)at the bottom of the loop, Ntrack is stronger than mgthe ball falls off the track if Ntrack= 0

A girl with a mass of 27 kg is playing on a swing. There are three main forces acting on her at any time: gravity, force due to centripetal acceleration, and the tension in the swing's chain (ignore the effects of air resistance). At the instant shown in the image below, she is at the bottom of the swing and is traveling at a constant speed of 3 m/s. What is the tension in the swing's chain at this time? (Recall that g = 9.8 m/s2)
The gravitational force exerted on a baseball is 2.11 N down. A pitcher throws the ball horizontally with velocity 15.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 158 ms. The ball starts from rest. Through what distance does it move before its release? What are the magnitude and direction of the force the pitcher exerts on the ball? (Enter your magnitude to at least one decimal place.)

You have put a sonar device at the top of a frictionless inclined plane. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. For an angle below the horizontal of 9.74°, we see that our object has slid a distance 0.54 m, as measured along the incline itself. - Calculate the height change and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o e
On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.
