A 1.08 kg block B is moving with a speed of 2.27 m/s as it strikes the 0.29 kg sphere A which was at rest. If the coefficient of friction between the block and the floor is p = 0.26 and the speed of the sphere was 1.56 m/s immediately after impact, compute the distance (m) travelled by the block. Round off only on the final answer expressed in 3 decimal pllaces. momentum.png ...

Given: The 6-kg collar is attached to a spring that has an unstretched length of 2m and a stiffness K=9.3 N/m. If the collar is drawn to point B and released from rest as shown. 3 m A 4 m Please fill in the blank your answer with two decimal places (for example 123.45). Do not add the units in the blank A) The work done by the spring when the collar reaches point A UB-A. Joule= 44.85 B) The work done by the weight of the collar when it reaches point A, Ug(8-A), Joule= C) The velocity of the collar when it arrives at point A. v, m/s=

Learning Goal: To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speed. M B As shown, ball B, having a mass of 10.0 kg, is attached to the end of a rod whose mass can be neglected. Part A - Finding the final speed of the ball If the rod is 0.550 m long and subjected to a torque M = (2.45t² + 4.45) N-m, where t is in seconds, determine the speed of the ball when t= 3.10 s. The ball has a speed of v = 2.80 m/s when t = 0. Express your answer to three significant figures and include the appropriate units.

Q5. As shown in the image below, the 69-kg skier slides down the smooth slope for which the shape is given by the y(x) function on the image. If the skier passes point C (for which x = 6 m) with a speed of 9 m/s, determine the normal force exerted on him by the slope at point C. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. Take g = 9.81 m/s². B Your Answer: y = (0.03x² + 6) m A Answer units ·X

Under the man's pushing force P= 30.8 lb, the uniform cabinet is sliding on the ground with a constant acceleration of a. If the uniform cabinet has weight of 150 lb, and the coefficient of kinetic friction between the cabinet and the ground is Uk 0.14, determine acceleration a in ft/s2.

Those data are for questions 15 to 20 The 5-lb rod AB with a length of l=2 ft is hanging in the vertical position. A 2-lb block , sliding on a smooth horizontal surface with a velocity of 10 ft/s, strikes the rod at its end B. e = 0.8. The goal is to find the linear velocity of the block and the angular velocity of the bar just after collision. Step 5: Find the linear velocity of the block after impact. Give your answer in ft/s with 1 decimal.

Determine the speed of block in Q1 when it moves 2m up the slope using the Work and Energy method and calculate the power of the force P.  (If you can apply the principle of work and energy or conservation of enegry.)  Plus can you not use the required method for this question. Question 1: A 5kg block is pushed up along the slope as shown. The coefficient of kinetic friction is uk =0.2. Determine the speed of the block when it moves 2 m up the slope using Newton's Second Law. I also gave the answer for Q1 if it helps: V = 2.21m/s
