A cannon located at sea level fires a ball with initial speed 82 m/s and initial angle 45°.The ball lands in the water after traveling a horizontal distance 686 m. How much greater would the horizontal distance have been had the cannon been 30 m higher?

A projectile with an initial velocity of 59.0 m / s is launched at an angle of 35.0 ° above the horizontal. The projectile lands on a hillside 3.80 s later. Neglect air friction. (Suppose the + x axis goes to the right and the + y axis goes up along the page). (a) What is the velocity of the projectile at the highest point of its trajectory? (magnitude m / s and direction ° (counterclockwise from the + x axis) b) What is the straight-line distance from where the projectile was launched to where it hits its target?

A ball is launched from the ground with an initial velocity vF18.1 m/s at an angle of 39.5° above the horizontal. It hits a wall located a horizontal distance of 22.0 m from the launch point. (c) How long does it take for the ball to hit the wall? Provide your answer in seconds (s). Use 3 significant figures. Your Answer: Answer units

During volcanic eruptions, chunks of solid rock can be blasted out of the volcano; these projectiles are called volcanic bombs. The figure shows a cross section of Mt. Fuji, in Japan. (a) At what initial speed would a bomb have to be ejected, at angle 0 d = 10.0 km? Ignore, for the moment, the effects of air on the bomb's travel. (b) What would be the time of flight? 32° to the horizontal, from the vent at A in order to fall at the foot of the volcano at B, at vertical distance h = 3.40 km and horizontal distance (a) Number Units (b) Number Units

A baseball is hit from ground level with a speed of 50.0 m/s and at an angle of 53.10.Take g=10m/s2. At what two times is the baseball 35 m above the ground?

If a projectile is launched at 73 degrees above the horizontal at 57.9 m/s, what is the direction of the projectile’s acceleration?

A tennis ball is struck with an initial velocity of 30 m/s, 28 degrees above the horizontal.What is the vertical component of this initial velocity?

A cannonball is aimed 36.9° above the horizontal and is fired with an initial speed of 180 m/s at ground level.  How far away from the cannon will the cannonball hit the ground?

You launch a projectile at an initial speed of 38.8 m/s from the ground. After 5.10 seconds of flight, the projectile lands on the ground. At what angle above the horizontal was the projectile launched?

Serving at a speed of 170 km/h, a tennis player hits the ball at a height of 2.5 m and an angle below the horizontal. The base line is 11.9 m from the net, which is 0.91 m high. What is the angle such that the ball just crosses the net? Will the ball land in the service box, whose service line is 6.40 m from the net?
