Joan sees a stationary long-board 8.0 m in front of her. She decided to run to the long-board as fast as she can, jump on, and roll down the sidewalk. Joan has a mass of 75 kg and the long-board's mass is 25 kg. If Joan accelerates at a steady 1.0 m/s², what is the magnitude of the velocity of the long- board just after Joan jumps and lands on it?

From what might be a possible scene in the comic book The X-Men, the Juggernaut (mJ) is charging into Colossus (mC) and the two collide. The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.
A 5-kg cart moving to the right with a speed of 6 m/s collides with a concrete wall and rebounds with a speed of 2 m/s. What is the change in momentum of the cart? (a) 0 (b) 40 kg m/s (c) 40 kg m/s (d) 30 kg m/s (e) 10 kg m/s
A girl of mass mg is standing on a plank of mass mp. Both are 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 vgp to the right relative to the plank. (The subscript gp denotes the girl relative to plank.) (a) What is the velocity vpi of the plank relative to the surface of the ice? (b) What is the girls velocity vgi relative to the ice surface?
A rocket has total mass Mi = 360 kg, including Mfuel = 330 kg of fuel and oxidizer. In interstellar space, it starts from rest at the position x = 0, turns on its engine at time t = 0, and puts out exhaust with relative speed ve = 1 500 m/s at the constant rate k = 2.50 kg/s. The fuel will last for a burn time of Tb = Mfuel/k = 330 kg/(2.5 kg/s) = 132 s. (a) Show that during the burn the velocity of the rocket as a function of time is given by v(t)=veln(1ktMi) (b) Make a graph of the velocity of the rocket as a function of time for times running from 0 to 132 s. (c) Show that the acceleration of the rocket is a(t)=kveMikt (d) Graph the acceleration as a function of time. (c) Show that the position of the rocket is x(t)=ve(Mikt)ln(1ktMi)+vet (f) Graph the position during the burn as a function of time.
Joan sees a stationary long-board 8.0 m in front of her. She decided to run to the long-board as fast as she can, jump on, and roll down the sidewalk. Joan has a mass of 75 kg and the long-board's mass is 25 kg. If Joan accelerates at a steady 1.0 m/s2, what is the magnitude of the velocity of the long-board just before Joan jumps and lands on it?
A 81.4 kg toy rocket is sent flying straight up into the air with an acceleration of 4.20 m/s2. After 4.70 s it explodes and breaks apart into two pieces. The heavier piece has a mass of 66.0 kg. If the lighter piece is able to reach a maximum height of 168 m above the ground, what is the speed of the heavier piece of the toy rocket just after the explosion?
You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 76.3 kg, and the sleds mass is 10.8 kg. The sled is moving by itself on the ice at 3.07 m/s. You parachute vertically down onto the sled, and land gently. What is the sleds velocity with you now on it? 0.49 m/s 0.44 m/s 0.38 m/s 0.23 m/s
A 50-kg girl is standing on a 139-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.64 m/s to the right relative to the plank. What is the velocity of the plank relative to the ice surface? Submit Answer Tries 0/10
Identical twins, each with mass 62.0 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg.
