A penguin of mass 6kg swims with a velocity of 1.79 m/s in the +x direction. The penguin then glides onto a small chunk of ice of mass 2000kg initially at rest. What is the final velocity of the ice and the penguin together?

An exploding coconut with a total mass of M breaks into three pieces.  Piece C has a mass of 0.3M and piece B has a mass of 0.2M.  If piece C has a velocity vfC= 7.9 m/s, determine the velocity of piece A, vfA

An ice skater with a mass of 48.0 kg is gliding across a smooth lake with a speed of 2.85 m/s when she hits a spot of ice covered with snow. After a time of 7.75 s she has slowed to a stop. Using your knowledge of momentum, determine the magnitude of the average force of friction acting on the ice skater while she slows to a stop.

A firework is launched and has a strictly vertical trajectory. It has velocity of 30 m/s right before it explodes. After it explodes, it instantaneously splits into three projectiles of equal mass. One of the projectiles continues to travel straight upwards with a velocity of 50 m/s. The right-most projectile now has an upward velocity of 45 m/s at 25◦ right of vertical. What is the final velocity of the left-most projectile?

Dan is gliding on his skateboard at 2.56 m/sm/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6.22 m/sm/s (as measured by an observer on the ground). Dan's mass is 42.1 kgkg and the skateboard's mass is 5.99 kgkg . If the jump requires 0.122 ss to complete, what average force did Dan exert on the skateboard?

suppose that car 1 has a mass of 0.301+-0.0001kg, and initial speed of 2.12+-0.03 m/s in the positive x direction. car 2 of mass 0.305+-0.0001kg is initially stationary. the two cars collide. after the collision, car 1 comes to a stop, and car 2 has a speed of 1.97+-0.02 m/s in the positive x direction. calculate the total final kinetic energy of the two car system with uncertainty.

A 44.0-kg girl is standing on a 157-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.461 m/s relative to the plank. (a) What is the velocity of the plank relative to the ice surface? 1 m/s (b) What is the girl's velocity relative to the ice surface? 1 m/s Need Help? Read It Master It

Q.20. As given in the figure, the surface is friction less. The two objects collide, stick together and move together after the collision. Find the magnitude of final velocity in m/s? (write numerical value only) m, =3 Kg Vi =8m/s m = +kg Syu8 = Vz =10m/s Me

A 46,0-kg girl is standing on a 161-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.461 m/s relative to the plank. (a) What is the velocity of the plank relative to the ice surface? 1 m/s (b) What is the gitt's velocity relative to the ice surface?
