In the gure. a 4.2 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is v0 = 7.3 m/s. the height difference is h = 0.97 m, and pk = 0.558. Find d. y=0-'\\ Number n Units v In the figure, two blocks are connected over a pulley. The mass of block A is 5.10 kg and the coefficient of kinetic friction between A and the incline is 0.220. Angle 0 of the incline is 45.0% Block A slides down the incline at constant speed. What is the mass of block B? Frictionless, massless pulley B Number i UnitsIn the figure here, a ball is thrown up onto a roof, landing 3.70 s later at height h = 19.0 m above the release level. The ball's path just before landing is angled at 0 = 60.0' with the roof. (a) Find the horizontal distance d it travels. (Hint: One way is to reverse the motion, as if it is on a video.) What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial velocity? A d (a) Number i Unit (b) Number i Unit (c) Number i UnitIn the figure, block 1 of mass mj slides from rest along a frictionless ramp from height h = 2.7 m and then collides with stationary block 2, which has mass my = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction /k is 0.1 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? Frictionless 12 (a) Number Unit (b) Number i UnitA soccer ball is kicked from the ground with an initial speed of 18.9 m/s at an upward angle of 48.5". A player 53.3 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s2. Number i Unit
