Inline roller skater is skating on a curved path as shown. The curved path is described as y= f(x)3D 0.18x2. The velocity of the skater once he reaches point A is 4.9 m/s which is increasing at rate of 0.54 m/s2. Calculate the magnitude and direction of skater's acceleration at point A. Note that yA = 9.3 m. Answer:
In the game of tetherball, a ball is hung from a vertical pole via a 0.75m rope. The rope is allowed to pivot freely from the top of the pole so the ball can swing around the pole. If the angle of the rope is 30° with respect to the pole, how much time does it take the ball to make one complete revolution around the pole?

You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. 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. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - 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 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0

Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. A 9.0 kg gibbon has an arm length (hand to shoulder) of 0.60 m. We can model its motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. At the lowest point of its swing, the gibbon is moving at 3.5 m/s. What upward force must a branch provide to support the swinging gibbon?
