A train departs from its station at a constant acceleration of 5m/s2. What is the speed of the train at the end of 20 seconds

Using the periodic table entry below, how many neutrons does the most common isotope of hydrogen have?

How much is required to accelerate a 5kg mass at 20 m/s2

A 95 kg clock initially at rest on a horizontal floor requires a 650 n horizontal force to set it in motion. after the clock is in motion, a horizontal force of 560 n keeps it moving with a constant velocity.

1. third law Every applied force is opposed by an equal force. 2. second law A force must be applied to change an object's velocity. 3. first law Acceleration is affected by mass.

A pool ball rolling at 10m/s[w] strikes a cushion and then rebounds at a velocity of 10m/s[s]. what is the change in velocity of the pool ball?

What does it mean when the mark on the ramrod disappears into the barrel of the muzzleloader?

Explain the relationship between speed, velocity and acceleration
