In a football match, a player kicked 400 grams of football with a speed of 70 miles per hour at an angle of 30 degrees to make a goal. But the ball was stopped by the goalkeeper after 2 seconds. It took 2 milliseconds for the goalkeeper to make the ball at rest in his hands. Assuming constant force was applied by the goalkeeper during this time, what will be the value of force applied by the goalkeeper? 666 N 1752 N 3920 N 1490 N 000
