In a lacrosse game a ball is thrown with a force of 2000 N. The throwing force acted for 0.8 seconds. another player stopped the ball in 0.3 seconds with their helmet. What force did their helmet. What force did their helmet use to stop the ball.

Abaseball player hits a foul ball vertically off his bat. the ball goes straight up and then falls back down. just before it hits the ground, the catcher catches the ball. the height of the ball t seconds after it is struck can be described by the function s(t)=-16t^2+80 t + 1 here, the height of the ball above the ground, s, is measured in feet. find the function, v(t), that describes the velocity of the ball at time t. v(t) = click here to preview your answer. find the function, a(t), that describes the acceleration of the ball at time t. a(t) = click here to preview your answer.
