Answer:
m = 7.48 kg
Explanation:
force (f) = 11,500 N
length of barrel (s) = 1.7 m
angle above the ground = 49.3 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
initial velocity (u) = 0 m/s
final velocity (v) = 72.3 m/s
mass (m) = ?
force = mass (m) x acceleration (a)
acceleration (a) = force / mass (m)
acceleration (a) = 11500 / m
applying the equation of motion , we can get the mass
5227.3 = 0 +
m =
m = 7.48 kg
