A projectile is fired from point A at the edge of a cliff, whose initial velocity components are v0x = 60.0m / s and v0y = 175m / s

A projectile is launched from point A with speed vo = 38 m/s. Determine the value of the launch angle a which maximizes the range R indicated in the figure. Determine the corresponding value R. Vo = 38 m/s A Answers: α = α R= i i 127 m- 15.8 m R 3 B

A baseball is thrown from an outfielder to the second baseman on a level field. The ball is in the air for a time At = 3.50 s and travels a horizontal distance of 92.0 m %3D before being caught at the same height it was thrown from. Ignore air resistance. a) What are the x- and y-components of the ball's initial velocity? b) What is the maximum height of the ball? c) When is the ball traveling at an angle of 0 = -26.0°?

In a ballistic pendulum lab we used the law of projectile to determine the initial velocity. The ball was released with some initial speed V from the table, the table has an altitude of 1.1 m and the ball land 2.3 m away. What is the muzzle velocity of the ball as it shot from the gun? 4.9 m/s O 7.0 m/s O 6.1 m/s O 8.0 m/s

During a rockburst (violent rock failure underground), a rock block was ejected as a projectile from the tunnel wall at a height of 1.5 m and the block landed on the floor at a distance of 2.5 m from the left wall. Determine the ejection velocity Ve for theta = 20degrees.

Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?

A punter kicks a ball at an angle of 75 degrees with an initial velocity of 15 m/s. What is the maximum height of the ball? (Assume his foot hits the ball 1 meter above the ground). Include a drawing and all steps. Use the projectile motion equations.

Problem 4 An object is launched at a velocity of 25 m/s in a direction making an angle of 20° upward with the horizontal. What is the maximum height reached by the object?
