A ball rolls down a ramp for 5 seconds. It accelerated 3m/s2 until it reached 28 m/s. What was the ball’s initial velocity? (select the correct equation)

Option 4 is correct ,

Explanation:

By the question,

Time (t) = 5 sec

accelation (a) = 3m/s^2

final velocity (Vf) = 28m/s

we know that ,

so, doing cross multiplication , we get:-

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.
