Aprojectile is launched at an angle into the air at velocity v and angle θ. determine its vertical acceleration.

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?
