Sally finds herself stranded on a frozen pond so slippery that she can't stand up or walk on it. To save herself, she throws one of her heavy boots horizontally, directly away from the closest shore. Sally's mass is 57.0 kg, the boot's mass is 5.0 kg, and Sally throws the boot with speed equal to 30.0 m/s. For all parts, assume the ice is frictionless. 1) What is Sally's speed immediately after throwing the boot? m/s Submit You currently have 2 submissions for this question.

The center of mass is located at the point where she threw the boot. The center of mass is located halfway between Sally and the boot. The center of mass is where Sally is.

Your submissions: A Submitted: Thursday, March 30 at 5:27 PM Feedback: Since the system starts at rest, the center of mass will not move. Therefore, the center of mass is located at the point where she threw the boot. 3) How long does it take Sally to reach the shore, a distance of 35.0 m away from where she threw the boot? s Submit You currently have 1 submissions for this question.

The wooden block is initially at rest, and is connected to a spring with k = 800 N/m. The other end of the spring is attached to an immovable wall. What is the maximum compression of the spring? Note: You may assume that the spring is massless and that the collision between the bullet and the wooden block is completely inelastic. m Submit You currently have 0 submissions for this question.

N E III A blue car with mass m = 424 kg is moving east with a speed of v = 19 m/s and collides with a purple truck with mass m = 1276 kg that is moving south with a speed of v = 13 m/s. The two collide and lock together after the collision. 1) What is the magnitude of the initial momentum of the car? kg-m/s Submit You currently have 0 submissions for this question.
