A heavy ball with a weight of 150 N is hung from the ceiling of a lecture hall on a 4.6-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.1 m/s as it passes through the lowest point. What is the tension in the rope at that point?
Answers: 3
where T is the tension on the rope, m is the mass of the ball, v is the speed of the ball of the ball at the lowest point and r is the length of the ball.
where F is the force and g is acceleration due to gravity. Now replacing m with the above in the dirst equation then

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
