hello can someone please help me answer these questions ASAP!!! Thanks in advance!!!!

5. An 80 kg man standing at rest on a smooth, level ice surface throws a 200 g ball horizontally with a speed of 25 m/s, relative to Earth. (a) With what speed and in what direction does the man move? (3 marks) (b) If the man throws six such balls every 5.0 s, what is the average force acting on him? (3 marks) 6. During a free dance program in figure skating, Victor (m = 71 kg) glides at 2.1 m/s to a stationary Shae-Lynn (52 kg) and hangs on. How far will the pair slide after the "collision" if coefficient of kinetic friction / between their skates and the ice is 0.052? (6 marks) 7. A 34-g bullet travelling at 120 m/s embeds itself in a wooden block on a smooth surface. The block then slides toward a spring and collides with it. The block compresses the spring (k = 99 N/m) a maximum of 1.2 cm. Calculate the mass of the block of wood. (6 marks) Hint: You will need to use systems of equations to solve this problem.8. A steel ball of mass 0.50 kg, moving with a velocity 2.0 m/s, strikes a second ball of mass 0.30 kg, initially at rest. The collision is a glancing one, causing the first ball to be deflected by an angle of 30", with a speed of 1.50 m/s. Determine the velocity of the second ball after the collision, giving both its speed and direction. (6 marks) 1 = 1.50 m/'s 1 30 2 v = 2.0 m/s V,=0 2
