Spot the dog is running after a ball. in 22m, he accelerates at a constant rate, and his velocity increases from 5.0m/s to 11m/s. what was his acceleration.

Here it is given that speed of the dog will increase from 5 m/s to 11 m/s in order to cover the distance of 22 m

so here we can use kinematics to find the acceleration

now we will have

so here it will accelerate with a = 2.18 m/s^2

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.
