A light block of mass m and a heavy block of mass M are attached to the ends of a rope. A student holds the heavier block and lets the lighter block hang below it, as shown in Figure Q5.6. Then she lets go. Air resistance can be neglected.
Figure Q5.6
a. What is the tension in the rope while the blocks are falling, before either hits the ground?
b. Would your answer be different if she had been holding the lighter block initially?

(a) How much does the suited astronaut weigh on Earth? (b) What is the mass on the Moon? On Earth?arrow_forwardA ball hanging from a light string or rod can be used as an accelerometer (a device that measures acceleration) as shown in Figure P5.18. What force causes the deflection of the ball? Is the cart in the lower part of the photo an inertial reference frame? How can the balls deflection be used to find the carts acceleration? In which direction is the cart accelerating? Explain your answers.arrow_forward
- a. You are a newly graduated astronaut preparing for your first trip into space. Plans call for your spacecraft to reach a velocity of 500. m/s after 2.40 minutes. If you weigh 735 N, what force will be exerted on your body? Assume the acceleration is constant. b. A car is traveling at 25 m/s when the driver spots a large pothole in the road a distance of 30 m ahead. He immediately applies the brakes. If his acceleration is -27 m/s^2, does he manage to stop before reaching the pothole?arrow_forwardA 20.0 kg block is placed on an incline that makes an angle of 30.0°. A man pushes up on the block parallel to the incline to keep it from sliding down. He must apply a force of 50.0 N. A. What is the coefficient of friction? B. If the man lets go of the block, what is its acceleration? C. How far will the block slide down the incline in 2.00 s?arrow_forwardBox A has mass 4.50 kg, and box B has mass 13.0 kg. The coefficient of kinetic friction between box B and the horizontal surface is 0.20. a. What is the tension in each chain when box B is moving to the right and speeding up with an acceleration of 2.20 m/s2? b. What is the mass of box C if box B has this acceleration? C A.arrow_forward
- A horizontal rope is tied to a 50 kg box on frictionless ice. What is the tension in the rope ifa. The box is at rest?b. The box moves at a steady 5.0 m/s?c. The box has νx = 5.0 m/s and ax = 5.0 m/s2?arrow_forward2. A 1,480-N crate is being pushed across a level floor at a constant speed by a force F of 370 N at an angle of 20.0° below the horizontal, as shown in the figure a below. The floor has some amount of friction. 20.0° a a. Draw a free body diagram of all the forces on the crate. b. Write out one equation for the y component of the resultant force. Hint: The crate does not move in the y direction. Write out one equation for the x component of the resultant force. Hint: the crate moves in the x direction. C. d. Determine the Normal force. e. What is the coefficient of kinetic friction between the crate and the floor? (Enter vour answer to at least three decimal places.)arrow_forwardStarting from rest, a 150 kg body experiences a force of 100 newtons acting on it in a direction parallel to the positive x-axis and a force of 150 newtons acting at 55° with respect to the positive x-axis. a. What is the net force acting on the body? Include direction. b. What is the acceleration of the body? c. What velocity does it reach after 5 seconds?arrow_forward
- It takes the elevator in a skyscraper 5.0 s to reach its cruising speed of 12 m/s. A 65 kg passenger gets aboard on the ground floor. Part A What is the passenger's weight before the elevator starts moving? Express your answer with the appropriate units. Part B What is the passenger's weight while the elevator is speeding up? Express your answer with the appropriate units. Part C What is the passenger's weight after the elevator reaches its cruising speed? Express your answer with the appropriate units.arrow_forwardActivity 2.4. B. HOW MUCH DO I WEIGH? A. You stand on a bathroom scale that rests on the floor inside the elevator. Standing on the scale compresses the internal springs and activates a dial that indicates your weight in newtons. When the elevator is at rest, the scales reading is 550 N. The the elevator begins to move upward with a constant acceleration of 2.5m/s?. 4.
