Determine the velocity required for a moving object 2.00 x 10# m above the surface of Mars to escape from Mars's gravity. The mass of Mars is 6.42 x 102 kg, and its radius is 3.40 x 10 m. V. = x10 msIThree clowns move a 355 kg crate 12.0 m to the right across a smooth floor. Take the positive horizontal and vertical directions to be right and up, respectively. Moe pushes to the right with a force of 475 N, Larry pushes to the left with 285 N. and Curly pushes straight down with 505 N. Calculate the work W done by each of the clowns. Assume friction is negligible. W Move = W Larry = W Curly =A book slides across a level, carpeted floor with an initial speed of 3.85 m/s and comes to rest after 2.75 m. Calculate the coefficient of kinetic friction / between the book and the carpet. Assume the only forces acting on the book are friction, weight, and the normal force. H =
