hello I need help solving those questions please thank you so much in advance!

'l a High-speed stroboscopic photographs show that the head of a golf club of mass 1909 is traveling at 50.8m/s just before it strikes a 47.09 golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 42.8m/s. Calculate the speed of the golf ball just after impact. Submit Answer Tries 0/10 0 a The mass of the blue (lower) puck in the figure below is 21.1 percent greater than the mass of the green (upper) one. Before colliding, the pucks approach each other with equal and opposite momenta, and the green puck has an initial speed of 10.3m/s. The angle 9 = 32.8. Calculate the speed of the blue puck after the collision if half the kinetic energy is lost during the collision. Submit Answer Tries 0/10 What is the speed of the green puck aer the collision. Submit Answer Tries 0/10 0 a An m1 = 7.459 bullet is red into a m2 = 2.41kg block that is initially at rest at the edge of a frictionless table of height h = 1.16m, as seen in the figure below. The bullet remains in the block, and after impact the block lands 0' = 2.48m from the bottom of the table. Calculate the initial speed of the bullet. Submit Answer Tries 0/10
