In a crash test, a 2,500 kg car hits a concrete barrier at 1.3 m/s2. If the car strikes the barrier with a force of 3,250 N, how much resistance force does the barrier provide? N This pair of forces is an example of Newton’s law of motion.
What will happen to a test dummy during a crash test if its seatbelt is not buckled?

Annie has a soccer ball and a kickball. She kicks each ball with the same force. The soccer ball accelerates at 3 m/s2, and the kickball accelerates at 5 m/s2.Use Newton’s laws to describe why the kickball has a greater acceleration.
According to Newton's second law, force equals mass times acceleration (F=ma). When the same force is applied to two objects, the object with the smaller mass will experience a greater acceleration. Since the kickball has a greater acceleration (5 m/s2) compared to the soccer ball (3 m/s2), the kickball must have less mass than the soccer ball.

A 2.9 kg model rocket accelerates at 15.3 m/s2 with a force of 44 N. Before launch, the model rocket was not moving. After the solid rocket engine ignited, hot gases were pushed out from the rocket engine nozzle and propelled the rocket toward the sky.Which of Newton’s laws apply in this example? Select three options.
