Josh and Taylor, standing face-to-face on frictionless ice, push off each other, causing each to slide backward. Josh is much bigger than Taylor. After the push, which of the two is moving faster?

Your friend's 11.1 g tassel hangs on a string from his rear-view mirror. When he accelerates from a stoplight, the tassel deflects backwards toward the rear of the car. If the tassel hangs at an angle of 6.89° relative to the vertical, what is the acceleration of the car?

Do Two skydivers are holding on to each other while falling straight down at a common terminal speed of 61.90 m/s. Suddenly, they push away from each other. Immediately after separation, the first skydiver, who has a mass m₁ of 94.80 kg, has a velocity U₁ with the following components ("straight down" corresponds to the positive z-axis). U1, y = 4.750 m/s U1,2 = 61.90 m/s What are the x- and y-components of the velocity v₂ of the second skydiver, whose mass m₂ is 57.70 kg, immediately after separation? Assume that there are no horizontal forces of air resistance acting on the skydivers.

Two blocks are positioned on surfaces, each inclined at the same angle of 55.7 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 2.73 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? a. 2.65 kg b. 3.97 kg c. 1.23 kg d. 5.96 kg

Two blocks are positioned on surfaces, each inclined at the same angle of 42.7 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 4.44 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2?     7.03 kg     2.94 kg     10.55 kg     4.69 kg

A 80 kg woman on roller skates pushes a 30 kg girl, also on roller skates, with a force of 100 N. The magnitude of the force exerted by the girl on the woman is O 200 N O 100 N O 50 N O 40 N O 38 N zero

A 60 kg block slides along the top of a 100 kg block.  The lighter block has an acceleration of 3.8 m/s2 when a horizontal force F= 390 N is applied.  Assuming there is no friction between the bottom 100 kg block and the horizontal frictionless surface but there is friction between the blocks.  Find the acceleration of the 100 kg block during the time the 60 kg block remains in contact.

Two blocks of masses 20 kg and 8 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 8-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.5 m/s 2 what is the tension in the connecting string between the blocks?

What If? How would your answers to parts (a) and (b) of this problem change if the 2.0 kg block was now stacked on top of the 1.0 kg block? Assume that the 2.0 kg block sticks to and does not slide on the 1.0 kg block when the system is accelerated. (Enter the acceleration in m/s2 to the right and the tension in N.)

Alice and Bob had car trouble. Their car broke down and Bob could not restart it. Alice got out to push the car and after some time she asked Bob if he would trade jobs with her for a while. Bob answered, "It won't matter if I do. I took physics, and I know that no matter how hard I push on the car, it will push back on me just as hard so I won't accomplish anything. That's Newton's Third Law and it is always true. It has been tested millions of times. It wouldn't matter if I pushed the car. I wouldn't be able to push it anywhere." Aside from the fact that his relationship with Alice is probably fınished, which of the following correctly explains a flaw in Bob's logic? The third law says that the two forces he is talking about are only approximately equal. The third law does not apply in this case because the car is on wheels. O The two forces he is talking about are on two different objects. Thw two forces will not be the same because the two masses are different. The third law only…
