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?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
