A 2.0 kg ball at the end of a 1.1 m string swings in a vertical plane. At its lowest point the ball is moving with a speed of 17 m/s. (a) What is its speed (in m/s) at the top of its path? m/s (b) What is the tension (in N) in the string when the ball is at the bottom and at the top of its path? bottom of its path top of its path N

A skier weighing 0.85 kN goes over a frictionless circular hill as shown. If the skier's speed at point A is 8.8 m/s, what is his speed at the top of the hill (point B)?

The tension in each rope of a swing at the lowest point is 412 N when a  36.0-kg girl is swinging. The two ropes are each 3.06 m long. What is the girl's speed at the lowest point?

A child of mass 25.0 kg tries to cross a river by swinging from a vine. The vine is 10.0 m long, and his speed at the bottom of the swing is 7.00 m/s. What is the tension in the vine at the lowest point? Your Answer: Answer Question 14 (3 points) units (Continue the above problem) What is the speed of the child at a point 1.00 meters above the bottom of the swing after passing it? ignore air resistance.

A stunt performer swings on a 34.0 m long rope initially inclined at an angle of 40.0° with the vertical. (Assume the rope has negligible mass.)   (a) What is the stunt performer's speed (in m/s) at the bottom of the swing if he starts from rest? m/s   (b) What is the stunt performer's speed (in m/s) at the bottom of the swing if instead he pushes off with a speed of 4.40 m/s? m/s

Maria sets up a simple track for her toy block (m 0.54 m Need Help? = (a) Neglecting friction, what is the speed of the block when it reaches the bottom of the curve (the beginning of the horizontal section of track)? 3.25 m/s 0.40 kg) as shown in the figure below. She holds the block at the top of the track, 0.54 m above the bottom, and releases it from rest. (b) If friction is present on the horizontal section of track and the block comes to a stop after traveling 0.82 m along the bottom, what is the magnitude of the friction force acting on the block? 2.11 X Your response differs from the correct answer by more than 10%. Double check your calculations. N Read It
