Q 11 please Q8:A ball of mass 0.5 kg is dropped from a height h=2.0 m above theground as shown in the figure. Find the speed of the ball when it is ata height y = 0.6 m above the ground.A. 4.2 m/sB. 5.2 m/sC. 6.1 m/sD. 2.8 m/sQ9:A 6.0 kg block initially at rest is pulled to the right along a horizontal surface by a constanthorizontal force of 12 N. The surfaces in contact have a coefficient of kinetic friction of 0.15.Find the speed of the block after it has moved 4.0 m.A. 1.78 m/sB. 1.46 m/sC. 2.06 m/sD. 2.30 m/sQ10: A block having a mass of 1.0 kg is given an initial velocity VA-1.6 m/s to the right and collideswith a spring whose mass is negligible and whose force constant is 40 N/m as shownAssuming the surface to be frictionless, calculate the maximum compression of the springafter the collision.A. 25 cmB. 22 cmC. 28 cmD. 19 cmQ11: Two blocks are connected by a light string that passes over a frictionless pulley as shown. Theblock of mass m₂ = 1.25 kg lies on a horizontal surface and is connected to a spring of forceconstant 30 N/m. The system is released from rest when the spring is unstretched. The hangingblock of mass m₂ = 0.5 kg falls a distance of 0.10 m before coming to rest. Calculate thecoefficient of kinetic friction between the mass m, and the horizontal surface.A. 0.43B. 0.37C. 0.32D. 0.28Reference
