picture in your mind a block that slides without friction down a ramp that is inclined at an angle (q) above the horizontal. Initially the block is at rest a distance (s) in meters (measured along the plane) from the bottom. Calculate the time (in seconds)

## Physics

The figure shows a 7 kg block being pulled along a frictionless floor by a cord that applies a force of constant magnitude 20 N but with an angle θ(t) that varies with time. When angle θ = 29°, at what rate is the block's acceleration changing if

## Physics

A block with a mass of m = 21 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1 = 9.5 N. The second has a magnitude of F2 = 19.5 N and acts on the

## physics

The mass of the heavier block is 28 kg and the mass of the lighter blocks is 14 kg and the magnitude of the force of the connecting string on the smaller block is 24 N. Assume: g = 9.8 m/s^2 and the horizontal surface on which the objects slide is
