Question 1 (1 point) A server at a family restaurant drops a 0.400 Kg dinner plate. The plate shatters into three pieces as shown below. The mass of pieceA is 60.0 g and the mass of piece B is 60.0 g. The speed of piece C is m/s. 4/ Enter your three-digit numerical value. Question 3 (1 point) A space shuttle astronaut has a mass of 110 kg with her space suit on. She is on a spacewalk and picks up a full can of spray with a mass of 20 kg. Relative to the space shuttle, she is at rest. She then holds the can directly in front of her centre of mass to avoid rotation and releases 3.0 kg of spray at a speed of 15 m/s. The astronaut's speed, relative to the space shuttle, when she has stopped spraying is approximately m/s. :l'v Enter your three-digit numerical value. Question 4 (1 point) A 39.1 g golf ball is hit with an initial velocity of 88.7 m/s at an angle of 28.0 up from the horizontal. The vertical component of the ball's momentum is kg.m/s. A Enter your three-digit numerical value.Question 7 (1 point) An open box car has a mass of 30,000 kg and is moving on a level, frictionless railway track at 4.00 m/s during a rainy day. As it rains, the open cart collects water. How will this affect the speed of the box car? Support your reasoning. r
