After rounding second base, a baseball player with a mass of 77 kg slides into third...
initiated his siue Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with a spring that has a spring constant of 100 N/m. What is the coefficient of kinetie friction between the surface and the block if the spring stretches by 3.2 em when you pull on the block at angle of 15° above the horizontal? Assume the block is moving with constant velocity
A 99.5-kg baseball player slides into second base. The coefficient of kinetic friction between the player and the ground is μk = 0.552. (a) What is the magnitude of the frictional force? (b) If the player comes to rest after 1.04 s, what is his initial speed?

A block of mass 0.528 kg slides with uniform velocity of 3.60 m/s on a horizontal frictionless surface. At some point, it strikes a horizontal spring in equilibrium. If the spring constant is k = 26.1 N/m, by how much will the spring be compressed by the time the block comes to rest? b. What is the amount of compression if the surface is rough under the spring, with coefficient of kinetic friction µk = 0.411?
Question 16 1 pts A 50-kg block is at rest on a 150 slope. A force of 250 N is acting on the block up the slope parallel to it. If the block does not slide up the slope, what is the minimum value of the coefficient of static friction between the block and the slope? 0.528 0.566 O 0.510 O 0.260 Question 17 1 pts A force of 50-N directed 30° above the horizontal is applied to a 10-kg...
This is a physics question about applying Newton's Laws. So the question involves a pulley system in which two blocks are connected by a string. One block is on a horizontal flat plane with a mass of 7.8kg. The block and horizontal surface has a coefficient of kinetic friction of .87. The second block is on an incline that has a 35 degree angle the block that is on this incline has a mass of 4.8 kg. This incline is...
