Jennifer works for an automaker and tests the safety performance of cars. she watches a 2,000-kilogram car crash into a wall with a force of 30,000 newtons. what’s the acceleration of the car at impact?

15m/s²

Explanation:

According to the newtons second law of motion,

Force = mass × acceleration

F = ma

Acceleration = Force/mass

Given Force = 30,000N

Mass = 2,000kg

Acceleration = 30,000/2,000

Acceleration = 15m/s²

Acceleration of the car after impact will be 15m/s²

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
