Answer:
The average force applied to the ball is 84N
Step-by-step explanation:
This problem bothers on the impulse of a force
Given data
Mass of ball m= 0.28kg
Initial speed u= 0m/s
Final speed v= 6m/s
Time of impact t= 0.02s
We know that the impulse of a force
Ft= mv-mu
Hence the force is
F= (mv-mu)/t
F=m(v-u)/t
F= 0.28(6-0)0.02
F= 1.68/0.02
F= 84N

Answer:D
y = 11
Plug 4 in for x.
3 + 2(4) = y
Multiply.
3 + 8 = y
Simplify.
11 = y
