A Chinese rocket has a mass burn rate of 3.8 kg every single second, and the resulting exhaust gas speed is 2.3 × 103 m/s. Determine the magnitude of the engine’s thrust. The thrust is essentially the force exerted, that in turn provides the needed lift.

Who was the first scientist to measure speed as distance over time?

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
