Can the magnitude of a vector ever be equal to one of its components? Review Problems Students have demonstrations in class tomorrow. You throw the ball upward so that the ball lands on the roof of the adjacent building 4. A block is given an initial speed of How long does it take the ball to return to the ground? How can this be done using only a meter stick and a calculator?

What is the origin of the force that causes you to stop? HW is to complete page and following: Estimate the rat’s displacement after the first 30 s? How high is the projectile above the ground below when it is at its highest point in the trajectory? Can it ever be less? A lever, as shown to the right has an Effort Arm EA of 1.

A person is swimming upstream such that they are not moving with respect to the shore. What is the initial velocity of the marble as it leaves the launching device?

What is the gravitational potential energy of the roller coaster while anguar the top of the hill? When would it be the same as when you are on the ground?

It is said that in ancient times a rich man with a bag of gold coins froze to death stranded on the surface of phyics frozen lake. Suppose that this boat is now aimed directly across the river. What will be the horizontal velocity of this baseball at the highest point of its trajectory?

How far away must a ship be if the cannonball is to hit the ship? A tennis ball is to be thrown horizontally from the top of a Xcceleration assumption you can make is that the rocket is going straight up. What is the magnitude of the frictional force acting on the lamp h as it slides across the table?

Since the time given is for bounce up and down split it in half. Is the change in kinetic energy reference-frame dependant?

What will be the velocity of the cart as it reaches the bottom of the incline? What will be the total kinetic energy of this system before the collision?

What is the arrow’s average velocity for the first After braking for a short time the velocity of the car is reduced to A cart, which has a mass of 2. Is this car going too fast to make it safely through the curve? What is the orbital velocity of Io about Jupiter?

What will be the total energy content of this rocket while orbiting Neptune at the given altitude? What is the average acceleration for the 20 s to 30 s time interval?

What will be the normal force acting on his sled? If he wishes to reach the bottom in 3. The cannon rests Two rowers, who can row at the same speed in still water, set off across a river at the same time.

If the coefficient of kinetic friction between a Calculate the period of a communications satellite of the earth that is at an altitude of km.

How long will it take for this car to stop? How can a rocket that is coasting through outer space, which is essentially a vacuum, accelerarion direction?

The weight of the engine is lbs. A ball is dropped from the top of a building to the ground below. What would the velocity of this rocket have to be phyics order for it to orbit Callisto at an altitude of 4, km?
