Cylinder c rests on a 4-kg platform a supported by a cord which passes over the pulleys d and e and is attached to a 4-kg block b. cylinder c has a mass m = 12 kg. the system is released from rest. problem 13.133.b - forces in mass and pulley system determine the force exerted by the cylinder on the platform. the force exerted by the cylinder is n.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Jasmine is diving off a 3-meter springboard. her height in meters above the water when she is x meters horizontally from the end of the board is approximated by the equation h=-x^2+3x+3. what is the maximum height jasmine will reach on her dive?
