Alex, Ben, and Chris are trying to move a heavy rock of mass 230 kg. Alex pulls the rock North with a force of 360 N, Ben pushes the rock East with a force of 510 N and Chris pulls the rock with a force of 520 N at an angle 20.0 degrees East of North. They end up moving the rock 2.8 meters 50.97 degrees North of East. In the following answer boxes, enter the work done by Alex, Ben and Chris respectively.
510.00

Blocks A (mass 3.00 kg) and B (mass 12.00 kg, to the right of A) move...

Blocks A (mass 3.00 kg) and B (mass 12.00 kg, to the right of A) move on a frictionless, horizontal surface. Initially, block B is moving to the left at 0.500 m/s and block A is moving to the right at 2.00 m/s. The blocks are equipped with ideal spring bumpers. The collision is head on, so all motion before and after it is along a straight line. Let +x be the direction of the initial motion of A. Find...

As your spaceship coasts toward Mars, you need to move a heavy load of 1200 kg along a hallway of the spacecraft that has a 90 degree right turn, without touching the walls, floor, or ceiling, by working remotely, using devices attached to the load that can be programmmed to fire blasts of compressed air for up to 1.0 s in any desired direction. During a blast the load is subjected to a force of 20 N. The center of...

The particle has a mass of 0.6 kg and is confined to move along the smooth horizontal slot due to the rotation of the arm OA. Assume the particle contacts only one side of the slot at any instant. The arm has an angular acceleration of θ¨ = 3 rad/s2 when θ˙ = 2 rad/s at θ = 30∘. (Figure 1) Part A Determine the magnitude of the force of the rod on the particle when θ = 30∘. Express...

A small rock with mass 0.30 kg k g is released from rest at point A A , which is at the top edge of a large, hemispherical bowl with radius R R = 0.48 m m (the figure (Figure 1)). Assume that the size of the rock is small compared to R R , so that the rock can be treated as a particle, and assume that the rock slides rather than rolls. The work done by friction on...
