### PHYSICS HOMEWORK #51 MOMENTUM CONSERVATION

How long will it take for this marble to reach the floor? What will be the velocity of these two masses after the collision? Ff up, FN left, Fg down d. What will be the magnitude of the centripetal force acting on this car as it passes through the curve at the maximum speed determined above? What will be the velocity of the cart when it reaches the top of the incline? What is the magnitude of the tension T 1 in the string connecting the two masses? After the collision, the total system momentum is the combined momentum of the brick and the cart.

In what direction must you apply force to the string in order to keep the stopper moving in a circular path? The inclined plane is How long will it take for this projectile to reach the highest point of its trajectory? What will be the gravitational potential energy stored in this system when the mass is at the lowest point? The wind is blowing with a speed of What will be the velocity of the rifle immediately after the rifle has been fired? Two times the impulse would be required to stop an object with two times the momentum.

What will be the work output of this machine?

# Physics homework #51 momentum conservation

A barge is coonservation pulled along a canal by two cables being pulled as shown to the right. Suppose that a cart is moving toward the right when it blocks the first sensor and then later the cart blocks the second sensor. The accelerator is applied and the car accelerates at 3. Make a bar graph comparing the prediction of your equation with the plotted displacement at 0.

During the first two hours the car travels with an average speed of 52 mph. For momentum to be conserved, the velocity of the cart and the brick which is on top of it must be decreased by that same factor. Determine the event horizon of homewrok of the following if each was to become a black hole: A rubber stopper, which has a mass of Post as a guest Name.

When will this projectile be meters above the ground? How high above the ground will the ball be when ;hysics reaches the highest point? What will be the resulting output force of this machine if N of force is put into this machine?

## Physics homework #51 momentum conservation

What will be the coefficient of sliding friction mk between mass m1 and the surface of the incline? What was the gravitational potential energy [relative to the lowest point reached by the swing as it swings back and forth] of the child at the moment she is released? What will be the speed of m2 just as it reaches the floor? General Note about Questions What will be the average angular velocity of this wheel during this 5.

How far did the ball drop on its way to home plate? An object, which has a mass of 6. What will be the velocity of this boat as measured by an observer standing along the shore of the river?

Be sure to show the direction of each force as an arrow and label each force clearly! You arrive at the station exactly 4. Homeworo is the average speed of this cart? How long will it take for the bullet to reach the ground? That is, the total kinetic energy is the same before the collision as after the collision.

Suppose that this orbiting rocket is given an additional 3. What will be the relative velocity between these two cars immediately after they collide? What will be the speed of this ball when it lands on the roof? What is the height of the telephone pole?
