you throw a ball upward with a seed of 14 m/s. what is the acceleration of the ball after it leaves your hand. ignore air restistance and provide an explanation for your answer.

Solutions

Expert Solution

the acceleration of the ball after it leaves your hand is = -g

                                                                              = -9.8 m/s 2

Since the only force act on ball after it leaves your hand is gravitational force.and it is in downward direction.

So, accleration of the ball a = -F / m

                                         = -mg / m

                                         = - g

1. You throw a 50kg ball upwards at 25m/s. The ball strikes the beginning of the spring when it's 8 meters in the air, then it begins to compress the spring. How far did the spring compress? The spring constant is 300 Newton/meter. Also, if the spring was not there, how far would have it gone up (set the final velocity to zero)? 2. You see a teeter-todder again. It's horizontal (balanced). A 100kg person sits 4 meters to the...
