a) A football game begins with a kickoff in which the ball travels a horizontal distance of 23.7 m and lands on the ground. Suppose the ball is punted from an initial height of 0.780 m. If the ball was kicked at an angle of 37.0° above the horizontal, what is the initial speed of the ball in this case? Give your answer to one decimal place. b) On a hot summer day, a young girl swings on a rope...
A player kicks a football at an angle of 46.0 ∘ with the horizontal, with an initial speed of 11.0 m/s . A second player standing at a distance of 28.0 m from the first (in the direction of the kick) starts running to meet the ball at the instant it is kicked. How fast must he run in order to catch the ball just before it hits the ground?
A football placekicker kicks the ball with a speed of 9.79 m/s at an angle of 60 degrees above the horizontal. How far does the ball travel horizontally from where the place kicker kicked it to where it landed on the ground?
3.58 Kicking an Extra Point. In Canadian football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 10.0 ft above the ground, and the ball is kicked from ground level, 36.0 ft horizontally from the bar (Fig. P3.58). Football regula- tions are stated in English units, but convert them to SI units for this problem. (a) There is a minimum angle above...
Practice Question 14 This question was not assigned to you A football player punts the ball at a 45.0° angle. When the ball returns to the ground, it will have a horizontal displacement of 74.0 m. What is the initial speed of the ball? (You may neglect the effect of the air, and assume that the ball is kicked from perfectly level ground.) Select the correct answer 20.7m/s O 20.6m/s O 20.5m/s O 26.9m/s O 24.1m/s
A ball is kicked with an initial horizontal speed of 13.1 m/s from a roof with a height of 3.3 m above the ground, as shown in the diagram. What horizontal distance will the ball travel before hitting the ground, in units of meters? assume the ground is flat assume that air resistance is negligible
A football is kicked from ground level with an initial velocity of 20.0 m/s at angle of 37.5° above the horizontal. How long is the football in the air before it hits the ground? Ignore air resistance.
A football is kicked from ground level with an initial velocity of 21.0 m/s at angle of 54.5° above the horizontal. How long, in seconds, is the football in the air before it hits the ground? Ignore air resistance.
A ball thrown horizontally at 28 m/s travels a horizontal distance of 60 m before hitting the ground. From what height was the ball thrown?
ball is thrown at a 60.0° angle above the horizontal across level ground. It is throw rom a height of 2.00 m above the ground with a speed of 16.0 m/s and experiences ppreciable air resistance. The time the ball remains in the air before striking the round is closest to
