A ball of mass 50g tied to the end of a 50cm inextensible string is whirled around in a vertical circle. find the tension in the string when the ball is at the top ofthe circle. Take g = 10m/s^2
A ball on the end of a string is whirled around in a horizontal circle of radius 0.340 m. The plane of the circle is 1.20 m above the ground. The string breaks and the ball lands 2.50 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion. Magnitude m/s Direction
A stone is tied to a string (length L = 1.10 m) and whirled in a circle at the same constant speed in two different ways. First, the circle is horizontal, and the string is nearly parallel to the ground. Next, the circle is vertical. In the vertical case, the maximum tension in the string is 15.0% larger than the tension that exists when the circle is horizontal. step 6: Draw the free-body diagram for the forces acting on the...
6. A ball is tied to the end of a cable of negligible mass. The ball is spun in a circle with a radius 2.00 m making 7.00 revolutions every 10.0 seconds. What are the (a) magnitude of the angular velocity in rad/s, (b) linear velocity in m/s, and (c) centripetal acceleration of the ball (in m/s')? Hint: 7 revolution divided by 10 seconds gives 0.7 rev/s, convert to rad/s
An air puck of mass 0.18 kg is tied to a string and allowed to revolve in a circle of radius 1.1 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of 1.3 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves (a) What is the tension in the string? (6) What is the force...
An air puck of mass 0.230 kg is tied to a string and allowed to revolve in a circle of radius 1.17 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of 1.03 kg is tied to it as seen in the figure below. The suspended mass remains in equilibrium while the puck on the tabletop revolves. What is the tension in the string?...
An air puck of mass 0.200 kg is tied to a string and allowed to revolve in a circle of radius 1.03 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of 1.22 kg is tied to it as seen in the figure below. The suspended mass remains in equilibrium while the puck on the tabletop revolves. What is the tension in the string?...
3. (5 points) A 35 g mass tied to a string oscillates as a pendulum. A student finds that 15 oscillations take 45 seconds. (acceleration due to gravity on the earth is 9.8 m/s) (a) Find the period of pendulum. (b) What is the length of the pendulum's string? (c) What is the period of the pendulum if the mass is doubled? (d) What is the period of the pendulum if the string length is halved? (e) What is the...
