Part A As part of a safety investigation, two 1300 kg cars traveling at 25 m/s are crashed into different barriers. Find the average force exerted on the car that hits a line of water barrels and takes 1.4 s to stop. Express your answer with the appropriate units. LA ?

The first bowler throws a 4.5 kg ball at 7.2 m/s. A second bowler throws a 6.4 kg ball. What speed must she beat to win the competition? Express your answer with the appropriate units. O ?

Why is this approach desirable? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help smaller The water balloon comes with a significant momentum Ap = FAt You must exert a over some acceleration time to bring the balloon to rest, according to larger force If you move your hand you can towards the balloon bring the balloon to rest over a time interval than if the balloon simply smacked with the balloon into a stationary hand. AF = pAt The force can be and achieve the same change in and the balloon won't break.Part A A small, 250 g cart is moving at 1.30 m/s on a frictionless track when it collides with a larger, 5.00 kg cart at rest.
