A bob on a 0.6 m long string is rotated in vertical circle. When the bob is in the position when the string makes 45 angle above horizontal, centripetal acceleration is 25 m/s2. Find tangential acceleration at this point and the speed of the bob in the top point of the circle.
A bob on a 2 m long string is rotated in vertical circle. In a point...
A bob on a 2 m long string is rotated in vertical circle. In a point where tangential acceleration is -6/s2, the centripetal acceleration is 25 m/s2. Find the maximum speed and the minimum speeds of the bob during this rotation.

I need help for part 2 please
1) A pendulum bob of mass m is attached to an ideal string of length L. The other end of the string is attached to a rigid hook. The bob is lifted along a circular are of radius L until it and the string makes an angle with the vertical, as shown. The bob is then released from rest. a) Prediction: If the magnitude of the tension in the string is measured to...

A bob of mass m is suspended from a fixed point with a massless string of length L (i.e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θ. 1. What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle θ from the vertical? Express your answer in terms of some or all of the variables...

In the apparatus shown above, one end of a string of length L is
attached to a block of mass M and the other end is connected to the
axle of a motor that rotates, causing the block to move in a circle
of radius R at a constant speed vT such that the string makes an
angle θ with the vertical. A student wants to use the apparatus to
make measurements and create a graph that can be used...

A pendulum consists of a 1.7-kg bob attached to a light 2.6-m-long string. While hanging at rest with the string vertical, the bob is struck a sharp horizontal blow, giving it a horizontal velocity of 5.0 m/s. At the instant the string makes an angle of 28° with the vertical, calculate the following (a) the speed m/s (b) the gravitational potential energy (relative to its value is at the lowest point) (c) the tension in the string? (d) What is...

A pendulum consists of a 2.2-kg bob attached to a light 2.0-m-long string. While hanging at rest with the string vertical, the bob is struck a sharp horizontal blow, giving it a horizontal velocity of 4.5 m/s. At the instant the string makes an angle of 27 degree with the vertical, calculate the following: (a) the speed m/s (b) the gravitational potential energy (relative to its value is at the lowest point) J (c) the tension in the string? N...

please give me detailed answer thank
you
Sam, whose mass is 71 kg , straps on his skis and starts down a 58 m -high, 20 degree frictionless slope. A strong headwind exerts a horizontal force of 200 N on him as he skies. Use work and energy to find Sam's speed at the bottom. Express your answer to two significant figures and include the appropriate units.

Please provide a free body diagram. Thank you. A car travels along an unbanked curve of radius R=50 m at a constant speed . The driver noticed that a 0.5 Kg toy hanging by a string on the rearview mirror moved sideways during the turn. The angle that the string makes with the vertical direction during this turn is 30 degrees. Find the speed of the car and the tension in the string The toy has centripetal acceleration- pointing towards...
