if a bullet of unknown mass is fired from a gun with 50m/s. such that the recoil of the gun is -0.3m/s if the mass of gun is 8 kg .find the mass of the bullet

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

Will mark as brainliest how does a catapult increase the trajectory of an object? ps. answer as if u were a 5th grader
