An object is tied to a string of length 1.00 m and is rotated in clockwise directionin a vertical circular path. The string breaks when the object is moving at a speedof v0= 15.0 m/s at point A, as shown in the figure. The center of the circle is 4.00 m fromthe ground. How long will it take for the object to hit the ground

We know that the moon Callisto revolves around Jupiter during a period of 17.0 days.17.0 days. The average distance from the center of Jupiter to the center of Callisto is 1.95×109 m.1.95×109 m. What is the acceleration ?a of Callisto due to its motion around Jupiter?

True or False An object moves in a circular path with constant speed v. Its velocity is constant, but its centripetal acceleration is changing.

A person drives a car around a circular, level cloverleaf with a radius of 85 m at a uniform speed of 10 m/sec. What is the acceleration of the car?

Car A rounds a curve of 107-m radius at a constant speed of 53 km/h. At the instant represented, car B is moving at 90 km/h but is slowing down at the rate of 3.0 m/s². Determine the velocity and acceleration of car A as observed from car B. Your answer is partially correct. Answer: VA/B = aA/B = 107 m 14.72 0 B CIDI i + -25 i + i 3 j) m/s j) m/s²

A well-thrown football is spinning at 5.9 rev/s. The widest point of the football is at the center of the laces, where the radius is 8.50 cm.  What is the magnitude of the centripetal acceleration of the laces in m/s2?

The amusement ride shown is initially travelling on a circular path in a horizontal plane about O with v = 5 ê ft/s and r = 30 ft. The length of the cable is then decreased by a constant rate of 2 ft/s. Determine the speed of the cart after 3 seconds.

An arrow is launched horizontally from the top of a pyramid that is 100 m above the ground as shown in figure 1. If the arrow strikes the ground at a point 65.0 m horizontally away from and below the point of release. What is the speed of the arrow (in m/s) just before it strikes the ground?

Doha kicks the ball in a parabolic path. The ball leaves the player’s foot with a speed of 20 m/s, making an angle of 40 o with the horizontal. a) Calculate the maximum height of its trajectory  b) Determine its velocity as it hits the ground again. Air resistance is negligible. c) How far from Darshan does the soccer ball land?

The figure below shows an object initially at point A traveling in the +x-direction. It turns in a circular path at constant speed until it is traveling in the +y-direction at point C. The quarter-circle arc from A to C is 245 m in length, and the particle moves from A to C in 38.0 s. Point B on the path is 35.0° below the x-axis. 0 35.0⁰ (a) What is the speed of the object (in m/s)? m/s Need Help? (b) What is the magnitude and direction of the acceleration when the object is at point B? (Enter the magnitude in m/s² and the direction in degrees counterclockwise from the +x-axis.) magnitude m/s² direction Read It counterclockwise from the +x-axis
