A projectile is launched at an angle of 45° with a velocity of 250 m/s. If air resistance is neglected, the magnitude of the horizontal velocity of the projectile at the time it reaches maximum altitude is equal to a. 250 m/s d. 0 m/s 175 m/s b. 200 m/s e. C. None of the choices

1) A kicker lines up to make a field goal attempt. If the ball leaves the kicker's foot at an initial speed of 20 m/s and an angle to the horizontal of 30.0°, Over what distances will the kick be successful (that it, over what range of distances will the ball clear the crossbar?) Assume the kick is in a domed stadium with no wind, and the ball is a point object. a.

student throws a heavy red ball horizontally from a balcony of a tall building with aninitial speed v0. At the same time, a second student throws a lighter blue ball horizontally fromthe same balcony with an initial speed v0 /2. Ignoring air resistance, which of the followingstatements must be true?a. The red ball hits the ground with the greater speed.b. Both balls hit the ground with the same vertical velocity component.c. Both balls hit the ground with the same angle of impactd. The balls reach the ground at the same instant.     More than one of the statements can be true.

A cannon ball was projected at an angle of 30deg with the horizontal with an initial velocity of 120m/s. 500m away there is a hill inclined at a certain angle with respect to the horizontal. 7 seconds after the cannon ball was released it hits the surface of the hill. Determine the distance from the bottom of the hill where the canon ball was landed and the inclination of the hill.

Trajectory of a Ball Due in 10 hours, 30 minutes A ball is shot from the ground into the air. At a height of 9.40 m, the velocity is observed to be v = (8.30 m/s) i + (7.00 m/s) j. What is the maximum height that the ball will rise? Submit Answer Tries 0/10 What will be the total horizontal distance traveled by the ball? Submit Answer Tries 0/10 What is the x-component of the final velocity of the ball? Submit Answer Tries 0/10 What is the y-component of the final velocity of the ball when it lands back on the ground?

12. A rescue airplane is rising at an angle of 30° above the horizontal with a speed of 300 m/s. It releases a survival package when it is at an altitude of 200 m. If air resistance is ignored, the time it takes for the package to fall to the ground is A. 24.6 s B. 28.3 s C. 23.1s D. 33.8 s E. 31.9 s

A golfer goes to chip the ball. The closest edge of the green is 60 m away and the furthest edge of the green is 80 m away. He hits the ball with an initial velocity of 30 m/s at a 40 degree angle. With this range, will the ball land on the green? O a. Yes O b. No
