This problem is solvable if we know Newton's three laws of motion.
Newton's first law of motion states that an object will continue at rest or in motion in a straight line at a constant velocity unless acted upon by an external force.
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. It is given by
Which one of the following is true, according to Newton’s laws of motion? Ignore friction.
A. A sports utility vehicle (SUV) hits a stationary motorcycle. Since it is stationary, the motorcycle sustains a greater force than the SUV does.
B. A semitrailer truck crashes all the way through a wall. Since the wall collapses, the wall sustains a greater force than the truck does.
C. Sam (18 years old) and his sister (9 years old) go ice skating. They push off against each other and fly apart. Sam flies off with the greater acceleration.
D. Two astronauts on a space walk are throwing a ball back and forth between each other. In this game of catch the distance between them remains constant.
E. None of the above is true, according to the third law.
