10. A snowboarder starts at the top of a 160. m tall hill with a velocity of 3.00 m/s. The portion of the hill covered with snow is essentially frictionless, but the flat, horizontal section at the base of the hill covered with mud is not. If the snowboarder masses in at 80.0 kg, and the coefficient of kinetic friction between board and mud is 0.750, how much distance is required for the snowboarder to come to rest?
88. You are in mission control in Florida, supervising a probe on its way to Mars. The most recent report indicates that the probe will soon need to fire a quick burst of its booster rocket to increase its speed by 5.2 m/s. You know that the spent fuel is ejected at a speed vfuel initial speed of the probe before firing, and that 10% of the probe's inertia is currently fuel. Your main worry is whether enough fuel is left for landing maneuvers. 0. CR = 800 m/s – v, where v, is the Vị -
1. A pulley device is used to hurl projectiles from a ramp (mk = 0.26) as ilustrated in the diagram. The 5.0-kg mass is accelerated from rest at the bottorm of the 4.0 m long ramp by a falling 20.0-kg mass suspended over a frictionless pulley. Just as the 5.0-kg mass reaches the top of the ramp, it detaches from the rope (neglect the mass of the rope) and becomes projected from the ramp. 4.0m M0.26 50kg 30 60m 20.0kg a.
