A 50 kg box hangs from a rope. What is the tension in the rope if: (b) The box moves up at a steady 5.0 m/s?

Three sleds are being pulled horizontally on frictionless horizontal ice using horizontal ropes

(Fig. E5.14). The pull is of magnitude 190 N. Find (a) the acceleration of the system

A light rope is attached to a block with mass 4.00 kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with mass m is suspended from the other end. When the blocks are released, the tension in the rope is 15.0 N. (c) Find m.

A 75.0-kg wrecking ball hangs from a uniform, heavy-duty chain of mass 26.0 kg. (b) What is the tension at a point three-fourths of the way up from the bottom of the chain?

A 50 kg box hangs from a rope. What is the tension in the rope if: (c) The box has vy = 5.0 m/s and is speeding up at 5.0 m/s^2

Astronauts in space 'weigh' themselves by oscillating on a spring. Suppose the position of an oscillating 75 kg astronaut is given by x = (0.30 m) sin ((𝝅 rad/s) X t), where t is in s. What force does the spring exert on the astronaut at (a) t = 1.0 s and (b) 1.5 s? Note that the angle of the sine function is in radians.

The mass of the sun is 2.0 x 10^30 kg. A 5.0 x 10^14 kg comet is 75 million kilometers from the sun. What is the magnitude of the comet's acceleration toward the sun?

A woman has a mass of 55 kg. (a) What is her weight while standing on earth?

It takes the elevator in a skyscraper 4.0 s to reach its cruising speed of 10 m/s. A 60 kg passenger gets aboard on the ground floor. What is the passenger's weight (c) After the elevator reaches its cruising speed?
