A 0.34kg tennis racket hits a 0.064kg tennis ball with a force of 8.0N forwards. If there was no force resisting the motion of the tennis racket, how fast would the tennis racket accelerate initially?

The acceleration of the tennis racket is .

Explanation:

Mass of tennis racket is 0.34 kg

Mass of a tennis ball is 0.064 kg

The force acting by the tennis racket by the tennis ball is 8 N. It is required to find the how fast would the tennis racket accelerate initially. Force is given by :

F = ma

So, the acceleration of the tennis racket is .

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.
