7. Which one of the following is true, according to Newton’s laws of motion? Ignore friction. (a) A sports utility vehicle (SUV) hits a stationarymotorcycle. Since it is stationary, the motorcycle sustains a greater forcethan the SUV does. (b) A semitrailer truck crashes all the way through awall. Since the wall collapses, the wall sustains a greater force than the truckdoes. (c) Sam (18 years old) and his sister (9 years old) go ice skating. Theypush off against each other and fl y apart. Sam fl ies off with the greater acceleration. (d) Two astronauts on a space walk are throwing a ball back andforth between each other. In this game of catch the distance between themremains constant.
