The figure shows a 100-kg block being released from rest from a height of 1.0 m. It then takes it 0.90 s to reach the floor. What is the mass m of the other block? The pulley has no appreciable mass or friction. m 100 kg 1.0 m

Below are six crates at rest on level surfaces. The crates have different masses and the frictional coefficients between the crates and the surfaces differ. The same external force is applied to each crate, but none of the crates move. Rank the crates on the basis of the frictional force acting on them. Largest to smallest

The figure shows the configuration of two identical bricks. In case 1 the bricks are placed end to end. In case 2 the bricks are stack on top of each other. What can you say about the kinetic friction when the bricks are pushed across a tabletop with constant speed?

The diagram shows all the forces on an object with mass m = magnitude of the acceleration of the object? 89 kg. What is the 480 N Select one: O 9.4 m/s? 30° O 6.0 m/s? 3.0 m/s? 120 N O 4.5 m/s sine and cosine reversed. Check that you didn't get 11.5 m/s? 240 N

Power As shown in the picture below, you and a friend are pushing a box horizontally. You can assume that you and your friend are both pushing completely horizontally in this case. Your combined push force (from you and your friend) is Push = 46.0 N. The box has a mass of 20.0 kg. You and your friend push the box a horizontal distance of 6.50 m. There is a force of friction between the ground and the box with a value of f = 28.0 N. Assume that initially the box is at rest when you and your friend start pushing it. What is the rate at which all of the forces do work on the box? This is another way of asking about Power. You'll need acceleration to find the time - but you have enough information to calculate the acceleration. Motion Воx Your answer should include the following: 2 Decimal Places Correct SI Units Appropriate sign (only needed for negative answers) Answers must be in the following format: Written out and NOT in scientific notation Acceptable: 278.40 Not Acceptable: 2.784 x…

The two masses shown in the figure are each initially 1.8 m above the ground, and the massless frictionless pulley is 4.8 m above the ground. 1.8 m 4.8 m 2.2 kg 3.6 kg

ved 161 A single cable is wrapped from the center of pulley A, around pulley B, and around pulley A. This cable is pulled downward at 2 m/s. At what speed does pulley B move upward? V = 1 S L= take a time derivitive 0-2 VAB+ VAC dB C WEIGHT 2 m/s de

Multiple-object systems without friction: The figure shows a 100-kg block being released from rest from a height of 1.0 m. It then takes it 0.90's to reach the floor. What is the mass m of the other block? The pulley has no appreciable mass or friction. (60 kg) m ------- 100 kg 1.0 m

After being release from rest, the objects move. When the blocks have moved 1 meter, calculate the speed of the blocks. 2.6 m/s 1.7 m/s 4.4 m/s 2.9 m/s 3.6 m/s

A 1490 N crate is resting on a table connected to a 400 N block through a frictionless pulley system as shown.  Friction between the crate and the table is enough to keep the system at rest.  The arrows show the forces that act on the crate and the block.
