Question 2
An air gun discharges an 8-grain pellet with a velocity of 1,100 ft/s. Calculate the kinetic energy.
KE =
ft-lb (Use 3 digits)



Help ASAP:,)

Answer 1

Answer:

KE = 21.5 ft-lb

Explanation:

KE = (1/2)m*v²

KE = .5*8*(1100ft/s)²

KE = 4840000 ft-grains

KE = (4840000 ft-grains)*(1lb/7000 grains)(1 lb/32.174 slugs)

KE = 21.5 ft-lb
