Question

nless otherwise stated, all objects are located near the Earth's surface, where g = 9.80 m/s2 .
A gun is fired and a 52 g bullet is accelerated to a muzzle speed of 130 m/s .

Part A

If the length of the gun barrel is 0.80 m , what is the magnitude of the accelerating force? (Assume the acceleration to be constant.)

show work please

Explanation / Answer

Applying work - energy theorem,

Work done by force = change in KE

F d = m v^2 /2 - 0


F ( 0.80) = (0.052) (130^2) / 2

F = 549.25 N ....Ans
