Imagine you are standing on a skateboard, initially motionless. You throw a medicine ball horizontally while on the skateboard and as a result you roll backward.

1. Model this situation by creating a complete momentum chart with the initial momentum at a time just before you throw the ball and the final momentum at a time just after letting go.

2. Consider the same scenario but use an interval with the final state chosen after the motion of the throw, but before the ball left your hands: Would you roll backward, forward, or remain in the same spot at that moment? Create a complete momentum chart to argue your case, and write out the reasoning for your answer.

Plz don't miss the momentum chart: WHAT SHOULD INCLUDE IN MOMENTUM CHART

Superman throws a golf ball horizontally so hard that after a while it hits him in the back! He concludes correctly that the ball must have flown once around the Earth! Calculate how long the ball was in the air. Use that the Moon takes 27.3 days to revolve once around Earth and is 380,000 km away from the Earth, while the radius of the Earth is 6370 km. Start each problem with a SKETCH carefully labeling all quantities you...

You throw a ball for your dog to fetch. The ball leaves your hand with a speed of 2 m/s, at an angle of 30◦ to the horizontal, and from a height of 1.5 m above the ground. The mass of the ball is 0.5 kg. Neglect air resistance in what follows. (a) What is the acceleration of the ball while it is in flight? Report it as a vector, that is, specify magnitude and direction (or vertical and horizontal...

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...
