A physical challenge. 3 homework problems I could not play!?

1) A 9500 kg car traveling at 12.4 m / s hits a car seconds rest. The two stick together and go e / ow / a speed of 4.1 m / s. What is the mass of the second car? 2) A golf ball of mass. O45 kg is struck on the tee at a speed of 37 m / s. The golf club has been in contact with the ball, 0027 seconds. a) Find the impulse imprted the golf ball. b) Find the average force exerted on the ball by the golf club. 3) A child in a boat throws a 6.3 kg package horizontally in the positive x direction with a speed of 10.0 m / s. Calculate the speed of the boat immediately after, assuming it was initially at rest. The weight of the child is 29 kg and the boat is 43 kg. Ignore water resistance.

1) the conservation of momentum: mass car 1 car * 1 = initial velocity (mass boxcar1 + boxcar2 mass) * final velocity 9500 * 12.4 = (9500 + boxcar2 mass) * 4.1 boxcar2 mass = 9500 * 12.4 / 4.1 to 9500 = 19,231.7 2)) stimulation imported the ball is the mass speed ball * ball = 0.45 * 37 = 16.65 b) = difference with the average strength of the moment or the time difference = 16.65/0.0027 = 6166.66 3) of Again, conservation of momentum 0 = mass * speed package package - (child of mass + mass of the boat) the boat speed * 6.3 * 10 = (43 +29) * Speed Boat boat's speed = 63/72 = 0.875 m / s speed boat is oriented horizontally in the negative x direction.
