A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 21.4 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 76.7 m), the block swings toward the outside of the curve. Then the string makes an angle θ with the vertical. Find θ.

A small sphere is hung by a string from the ceiling of a van. When the van is stationary, the sphere hangs vertically. However, when the van accelerates, the sphere swings backward so that the string makes an angle of with respect to the vertical. Find the acceleration of the van when e = 14.1º. Number 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...

In a scene from a television show, a van rolls down an incline and off a vertical cliff, falling into a river below. The van starts from rest and rolls down the incline, which makes an gle of 24.0° below the horizontal, with constant acceleration of 3.82 m/s2. After rolling down the incline a distance of 40.0 m, it reaches the u edge of the cliff which is 30.0 m above the river. (a) How much time (in s) does...

A large building has an inclined roof. The length of the roof is 45.5 m and the angle of the roof is 23.0° below horizontal. A worker on the roof lets go of a hammer from the peak of the roof. Starting from rest, it slides down the entire length of the roof with a constant acceleration of 3.83 m/s2. After leaving the edge of the roof, it falls a vertical distance of 30.5 m before hitting the ground. (a)...

Two blocks are connected to a string, and the string is hung over a pulley connected to the ceiling, as shown in the figure below. Two blocks, labeled m1 and m2, are connected to a string which is hung over a pulley connected to the ceiling. The pulley is of mass M and radius R. A block labeled m1 hangs suspended off the surface on the left side of the pulley. A block m2 is on the right side of...

Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with mass m1 = 16.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is a = 1.40 m/s2, and the tension in the segment of string attached to this block is T1. The hanging block has a mass of m2 = 23.5 kg, and the tension in the string attached to it is T2....

Horkovember 21 Vertical Spring 34,056.7 A block with mass m =6.9 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.24 m. While at this equilibrium position, the mass is then given an initial push downward at v = 5.1 m/s. The block oscillates on the spring without friction. 1) What is the spring constant of the spring? 282 N/m Submit Help 2) What is the oscillation frequency? 1.01 Hz Submit...

Part 1) A small block travels up a frictionless incline that is at an angle of 30.0°above the horizontal. The block has speed 4.26 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down? Part 2) Complete the following exercises. (Assume g = 9.80 m/s2.) (a) A small block is released from rest at...
