A football player kicks the ball so that it will have a "hang time" (time of flight) of 5.0 sec and land 50m away. If the ball leaves the player's foot 0.5 m above the ground,

(a) find the initial velocity of the ball

(b) find the velocity of the ball when it lands on the ground

A soccer player kicks the ball toward a goal that is 27.6 m in front of him. The ball leaves his foot at a speed of 18.5 m/s and an angle of 31.2° above the ground. Find the speed of the ball when the goalie catches it in front of the net. (Note: The answer is not 18.5 m/s.) I keep getting a final velocity of 13.92797m/s but its incorrect. Please show your work so I can see what I'm...

1.A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.70 × 10-3 s, and the force of the kick is given by F(t) = [(6.56 × 105)t - (3.86 × 108)t2] N for 0≤t≤1.70×10-3s, where t is in seconds. Find the magnitudes of the following: (a) the impulse on the ball due to the kick, (b) the average force on the ball from...

1. A soccer player will kick a ball 80 times during practice. Assume that the kicks are independent of each other, and the probability that he scores is 0.6 (60% chance that the ball goes into the goalpost and 40% chance that the ball does not go into the goalpost). Let X be the number of successful goals (number of scores) out of the 80 kicks. (a) What is the distribution of X? (b) Write the pmf f(x) and name...

Charlie kicks a soccer ball up a small incline. On the way up, ball’s acceleration has magnitude |a| = 0.45 m/s2 and is directed in downhill direction. Charlie kicks the ball at the bottom of the incline and then immediately start to walk up the incline with constant speed. Charlie performs twi different trials. a) In the first trial, Charlie kicks the ball with initial speed v0 = 3.4 m/s. Charlie is 2.3-m behind the ball when the ball is...

Maradona is, for those of you who don't follow football, history's best football player, as evidenced by his majestic goal against the Brits (do yourself a favour and google it... but after the test, of course). Suppose Maradona had the chance of setting up a football academy, which he would run himself and would occupy all of his time. He could set it up in 86, which was the peak of his career and footballing prowess. The monetary operating costs...
