A barefoot field-goal kicker imparts a speed
of 51 m/s to a football initially at rest.
If the football has a mass o f0.76 kg and the
time of contact with the ball is 0.035 s, what
is the force exerted by the ball on the kicker’s
foot?
Answer in units of N.

Thank you for the opportunity to help you with your question!

Force = mass x acceleration

acceleration in this case is 51/0.035 = 1457.14 m/s^2

Then the force = (0.76)(1457.14) = 1107.43 N

Please let me know if you need any clarification. I'm always happy to answer your questions.

Do they want the answer rounded to the nearest whole number?  Then the answer is 1107 N.
