Help me plzzz. i’ll give brainliest!!! 1. In the 1950's, an experimental train that had a mass of 2.50 x 10* kg, was powered across
a level track by a jet engine that produces a thrust of 5.00 x 10' N for a distance of 5.00 x
107 m. What is the final speed of the train if there was no friction?

2. A hockey puck is accelerated, using a hockey stick, over a smooth, level ice surface. The
puck has a mass of 0.400 kg and is moved by the stick for a distance of 0.800 m. What
was the average force applied to the puck if the final speed is 25.0 m/s?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
