At a time when mining asteroids has become feasible, astronauts have connected a line between their 3780-kg space tug and a 6940-kg asteroid. They pull on the asteroid with a force of 611 N. Initially the tug and the asteroid are at rest, 571 m apart. How much time does it take for the ship and the asteroid to meet?

Laila, who is a part of a critical patient's medical team was responsible for pushing a cart including a transport organ box containing a viable heart and other medical supplies needed for a heart transplant. In a rush, she pushed the 60.0 kg cart (this includes the supplies in it) down the long OR hallway. With the cart accelerating at 4.00 m/s/s with a force of 550 N, how much friction is acting on the cart + equipment due to its mass?

A person whose weight is  516 N is being pulled up vertically by a rope from the bottom of a cave that is  30.5 m deep. The maximum tension that the rope can withstand without breaking is  593 N. What is the shortest time, starting from rest, in which the person can be brought out of the cave?

The figure below is for a 7 kg box on a horizontal floor. Initially, you are pushing horizontally on the box and friction is opposing you. Then, you stop pushing the box. Use g = 10 m/s2. v(m/s) 6.0 4.5 3.0 1.5 0.3 0.6 0.9 t(s) Find the gravitational force acting on the box. Find the normal force acting on the box. Assume the frictional force is constant throughout the motion and find the frictional force. Assume the frictional force is constant throughout the motion and find your pushing force. Find the displacement of the box over the entire time shown.
