A ball is rolled up a ramp with an initial velocity of +6.0m/s. The ball experiences an acceleration of -2.0m/s^2. How can we determine at what time(s) the ball is +5.0m from its initial position on the ramp?

Apossible explanation for a set of facts that can be tested by further investigation is called

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
