A 2.50 kilogram workbook or textbook is forced against a horizontal spring of negligible mass and force constant 250 N/m, compressing the spring a distance of 0.250 meter. When released, the workbook slides on a horizontal tabletop with coefficient of kinetic friction uk=0.30. Use the work-energy theorem to obtain how far the textbook moves from its initial position before coming to rest.
A bumper car with mass m1 = 129 kg is moving to the right with a velocity of v1 = 4.50 m/s. A second bumper car with mass m2 = 86.0 kg is moving to the left with a velocity of v2 = -3.6 m/s. The two cars have an elastic collision. Suppose the surface..
During 9.93 seconds a motorcyclist changes his velocity from v1,x = -37.3 m/s and v1,y = 14.1 m/s to v2,x =-21.9 m/s and v2,y = 29.3 m/s. Find the components of the motorcycle's average acceleration during this process, aav,x and aav,y.
A major league pitcher can throw a baseball in excess of 41 m/s. If a ball is thrown horizontally at this speed, how much will it drop by time it reaches a catcher who is 17m away from the point of release.
