A hockey puck with mass 0.225 kg is at rest at the origin (x = 0) on the horizontal, frictionless surface of an ice rink. At time t=0 a player applies a force of 9.50 N on the puck, parallel to the positive x- axis. She continues to apply this force until t = 0.850 s. What are the position and speed of the puck at t = 0.850 s?

The vector position of a 3.50-g particle moving in the xy plane varies in time according to r rightarrow = (3i^ + 3j^ )t + 2j^ t2,where t is in seconds and r rightarrow is in centimeters. At the same time, the vector position of a 5.50-g particle varies asr2 rightarrow = 3i^ - 2i^t2 - 6j^ t. At t = 2.50 s, determine (a) the vector position of the center of mass, (b) the linear momentum of the system, (c) the velocity of the center of mass,(d) the acceleration of the center of mass, and (e) the net force exerted on the two-particle system.

You're driving along at 25m/s with your aunt's valuable antiques in the back of your pickup truck when suddenly you see a giant hole in the road 55 m ahead of you. Fortunately, your foot is right beside the brake and your reaction time is zero! If the coefficients of friction are μs =0.6 and uk =0.3, how much time does it take you to stop if you don't want the antiques to slide and be damaged?

Io, a satellite of Jupiter, is the most volcanically active moon or planet in the solar system. It has volcanoes that send plumes of matter over 500 km high. Due to the satellite's small mass, the acceleration due to gravity on Io is only 1.81 m/s2and Io has no appreciable atmosphere. Assume that there is no variation in gravity over the distance traveled. a)What must be the speed of material just as it leaves the volcano to reach an altitude of 380 km? b)If the gravitational potential energy is zero at the surface, what is the potential energy for a 33 kg fragment at its maximum height (500 km) on Io? c)How much would this gravitational potential energy be if it were at the same height (500 km) above earth?
s seen in Figure 1, a 63.2 kg glacier climber finds herself dangling over theedge of an ice cliff. Fortunately, she’s connected by a rope of negligible mass to a 1220kg rock located 48.6 m from the edge of the cliff, and help is on the way. Unfortunately,the ice is frictionless so she accelerates downward. What’s her acceleration and howmuch time does she have before the rock goes over the cliff?

Buster wants to demonstrate constantly-accelerated motion by letting a frictionless ice cube slide down an inclined plane. The ramp is L= 1.5 meters long. Buster can control the angle θ that the plane makes with the floor. He plans to release the ice cube from rest at the top of the ramp. If Buster wants the time the ice cube takes to completely slide down the ramp to bet= 2.0 s, what angle θ should the ramp make with the floor?
