What force is necessary to accelerate a 1250 kg car at a rate of4m/s squared

5000N

Explanation:

F=ma

(resultant) Force(N)= mass(kg) × acceleration (m/s^2)

input values into formula

F= 1250kg × 4m/s^2

F= 5000N

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.
