A 2g bullet leaves the barrel of a gun @ a speed of 500 m/s. If the length of the barrel is 50 cm, find the average force exerted on the bullet by the expanding gases as the bullet moves the length of the barrel. [I DONT KNOW THE FORMULAS OR HOW TO FIGURE THIS OUT. HELP PLEASE!]What are the formulas to find the force exerted on an object. [PLEASE READ FOR DETAILS]?
A bit more illumination:
Assuming the acceleration of the bullet to be constant,
a = V虏/2x = 500虏/(2*.5) = 250000 m/s虏
F = m*a = .002kg*250000 m/s虏 = 500 NWhat are the formulas to find the force exerted on an object. [PLEASE READ FOR DETAILS]?
force= mass x acceleration
