1-10. Newton's Laws of Motion An 18.6 N object rests on a smooth, horizontal surface. The object is acted upon by a force of 5.0 N applied at an angle of 53" above the horizontal. (a) What is the mass of the object? (b) What is the horizontal acceleration of the object? A 11-20. Work, Energy, and Energy Conservation A child with a mass of 40.0 kg is on the top of a slide that is 15.0 m long and inclined 35" along the horizontal. (a) Find the potential energy of the child at the top of the slide (b) How fast is the child going at the bottom of the slide if the slide is frictionless? 21-30. Momentum & Impulse A 46-kg skater is standing still in front of a wall. By pushing against the wall, she propels herself backward with a velocity of - 1.2 m/s. Her hands are in contact with the wall for 0.80 s. Ignore friction and wind resistance. Find the magnitude and direction of the average force she exerts on the wall (which has the same magnitude as, but opposite direction to, the force that the wall applies to her). 31-40. Collisions Batman (mass = 91 kg) jumps straight down from a bridge into a boat (mass = 510 kg) in which a criminal is fleeing. The velocity of the boat is initially 11 m/s. What is the velocity of the boat after Batman lands in it
