- A golfer hits a golf ball at an angle of 0 = 25° with initial velocity v = 110 ft/s. (a) Estimate As if the ball is hit the same velocity but the angle increased by 3°. (b) Estimate As if the ball is hit the same angle but the velocity increased by 7. (Give your answer to four decimal places.) (a) As (b) As =When a projectile's launch speed is doubled its range over level ground (for any launch angle) will be changed by a factor of what?A tennis player serves a tennis ball such that it is moving horizontally when it leaves the racquet. When the ball travels a horizontal distance of 15 m, it has dropped 57 cm from its original height when it left the racquet. What was the initial speed, in m/s, of the tennis ball? (Neglect air resistance.)
- An object is launched from the ground with an initial velocity and angle such that the maximum height achieved is equal to the total range of projectile. The tangent of the launch angle is?(1 point) A projectile is launched horizontally at 45 m/s from a tall building. If the projectile falls for 4 seconds, what is the magnitude of the resultant velocity the projectile hits the ground with?A ball thrown horizontally from a height of 1.2m hits the ground at a distance of 5.0m. What was the initial speed of the ball (in m/s)?
- A cannonball is fired off a cliff at an angle of 25 degrees with respect to the horizontal. The cliff is 80 m high. The initial speed of the rock is 50 m/s. (a) What is the range of the rock? (b) When the cannonball hits the ground what is the magnitude of its total velocity?Why an angle of 45 degrees gives the largest range possible in case of projectile motionUse the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second.Determine the maximum height and range of a projectile fired at a height of 8 feet above the ground with an initial speed of 800 feet per second and at an angle of 45° above the horizontal. (Round your answers to three decimal places.)

If the ball reaches a maximum height of 10 m, when kicked at an angle of 40° relative to the pitch, calculate the horizontal distance the ball travels before striking the ground again.An object is launched from the ground with an initial velocity and ankle such that the maximum height is equal to the total range of the projectile The tangent of the launch angle is?A projectile is fired with an initial speed of 40 m/s at angle of 23 degrees above the horizontal on a long flat firing range. Determine (1) the maximum vertical distance reached by the projectile, (2) the total time in the air, (3) the range of the projectile, (4) the velocity of the projectile 2 s after firing.
