A placekicker is about to kick a field goal. The ball is 25.3 m from the goalpost. The ball is kicked with an initial velocity of 20.8 m/s at an angle θ above the ground. Between what two angles, θ1 and θ2, will the ball clear the 2.86-m-high crossbar? Give your answers as (a) the smaller angle and (b) the larger angle. (Hint: The following trigonometric identities may be useful:
sec θ = 1/(cos θ) and sec2θ = 1 + tan2θ.)

Please help, I don't understand how to answer this question.

A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 21.7 m/s at an angle of 48.5° to the horizontal. (a) By how much does the ball clear or fall short of clearing the crossbar? (b) Does the ball approach the crossbar while still rising or while...

Activity 1: How far can a soccer player kick a soccer ball down field? Through the application of a linear function and a quadratic function and ignoring wind and air resistance one can describe the path of a soccer ball. These functions depend on two elements that are within the control of the player: velocity of the kick (v k ) and angle of the kick (?). A skilled high school soccer player can kick a soccer ball at speeds...

A place-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 21.2 m/s at an angle of 46.0° to the horizontal. (a) By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.) (b) Does the...

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.

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...
