A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/s

The coefficient of friction between the tires of Shirley's 1985 Ford Coupe and the dry pavement is 0.74. She doesn't drive the car often because it's becoming an antique, but she took it out for a gentle drive yesterday. While driving, she has to suddenly and forcefully brake when the light turned red. She probably shouldn't have been texting and driving! Her car (mass = 1.31x10³ kg) skids to a stop with an acceleration of m/s². Use the approximation g = 10 m/s².

The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.285 m while bringing a 950 kg car to rest from an initial speed of 1.7 m/s. How fast must a 2.5-g ping-pong ball move in order to have the same kinetic energy as a 145 g baseball moving at 35.0 m/s? m/s
The IKAROS spacecraft, launched in 2010, was designed to test the feasibility of solar sails for spacecraft propulsion. These large, ultralight sails are pushed on by the force of light from the sun, so the spacecraft doesn’t need to carry any fuel. The force on IKAROS’s sails was measured to be 1.12 mN. If this were the only force acting on the 290 kg spacecraft, by how much would its speed increase after 6 months of flight?
You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 42.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 18.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. What speed u (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.) V = x10 TOOLS mph
