hi, i need answers on the questions below. please provide explanation or solution if needed so i can better understand it. thank you so much.

8. When the three blocks in the figure are released from rest, they accelerate with a magnitude of 0.500 m/5^2. Block 1 has mass M, block 2 has 2M, and block 3 has 2M. What is the coefficient of kinetic friction between block 2 and the table? 2 3 a. 0.37 b. 0.41 C. 0.43 d. 0.51 e . No Answer 9. A particle with a mass of 10 kg is moving at a velocity of (3t^2 + 4t)i m/s. What would be the expression for the external net force F(t) being applied to the particle? Note that Note: [ and j are unit vectors O To (61 + 4) N O - (312 + 41) N O : ( 3+2 + 2 ) N Of (10r + 3) N2 10. Two objects, A and B, move at the same speed of 10 m/s with a mass of 10 kg and 5 kg respectively. Which of the two possesses greater inertia? a. A b. B C. Both Cannot be determined e. No Answer 11. A tennis ball of mass m is dropped from rest at point A, covering a height H, above a frictionless inclined plane at an angle 45 degrees to the horizontal as shown below. The moment the ball hits the inclined plane, it bounces horizontally at point B with the same speed with which it struck the plane and strikes the plane again at point C. In terms of g and H, determine the following quantities: Notes: m is the mass of the tennis ball. H is the distance between A and B. L is the straight-line distance from point B to C. g is the acceleration due to gravity. why = 0 A H B wir L 0 = 450A. The speed of the ball just after it first bounces off the plane at B. Ov = 2gH Ou = Way + 2gH Ov= (214 - 212) 2r O v = &H No Answer B. The time the ball is in flight between points B and C Of= 1 = 211 1 = O 1 = No AnswerC. The distance Lalong the plane from point B to C. OL = 1/2gH OL = 8V2Ht OL = 2/gH OL = 4/2H No Answer D. The speed of the ball just before it strikes the plane at point C. Ov = 10gH Ov = 20g Ov= 2gH Ov= 28 ( H - L) No
