A roofing shingle elevator is lifting a 35.0-kg package to the top of a building at constant speed. The angle between the elevator track and the horizontal is 75∘. The power of the elevator is 800 W. |
Part A Determine the vertical component of the speed with which the package is moving up. Assume no friction is exerted by the incline surface on the package. Express your answer with the appropriate units. |

You are pushing a 50 kg lawn mower with a force of 80 N at an angle of 45 degreesfrom the ground (the force points at 45 degreesinto the ground, like how you’d expect when you are pushing a lawn mower). What are the A) horizontal and B) vertical component of this force? The ground is pushing straight upwards at the lawn mower with some amount of normal force. The grassy lawn is also exerting a friction force against the...

The top edge of a thin rectangular metal plate with a mass of 2.80 kg is attached to a horizontal rod parallel to the edge of the plate. The plate hangs from this rod and is free to rotate about it without friction. The vertical height of the plate is 45.0 cm. The plate is pulled to the right until it makes an angle of 28.0° from vertical and then released from rest. At the same time, a piece of...

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...
