Question

a football player kicks a ball with the mass of 0.42 kg.the average acceleration of the foot ball was 14.8 m/s2. how much force did the kicker supply to the football?

6.22 m/s2

6.22 N

35.24 m/s2

35.24 N

Answer 1

Force = mass * acceleration

         = 0.42 * 14.8

Force = 6.22 N

Answer 2

Answer:

6.22 N

Explanation:

Givens

$m=0.42kg$

$a=14.8 m/s^{2}$

According to Second Newton's Law, a force is defined as

$F=ma$

That is, a force accelerates the mass which is being applied such force. So, in this case, we have to replace given values, and find $F$

$F=ma\\F=(0.42kg)(14.8m/s^{2})\\ F\approx 6.22N$

Therefore, the right answer is the second option.
