Answer:
The average force is 3142.86 N
Explanation:
We would apply the formula for calculating rate of change of momentum which is expressed as
F = m(v - u)/t
where
F is the force
m is the mass of the object
v - u is the change in velocity
t is the time
From the information given,
m = 0.02
v - u = 550
t = 3.5ms
We would convert from ms to s. Recall,
1 ms = 0.001 s
3.5ms = 3.5 x 0.001 = 0.0035
Thus,
F = 0.02(550)/0.0035
F = 3142.86 N
