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. (e) None of the above is true, according to the third law

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
