A soccer ball is at rest and is then kicked giving it a final velocity of 6.0 m/s. The ball has a mass of
1 answer:
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:
20
Step-by-step explanation:
c = 5(68-32)/9
c = 5(36)/9
c = 20
Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
