A projectile is fired at the edge of a cliff, with an initial velocity of 12 m/s at an angle of 40 degrees. If it takes the projectile to 10s to land on the bottom of the cliff, how far did it travel horizontally?
A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? What other angle gives the same range? For the pass using the smaller of the two angles, how long is the ball in the air?
A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?
A projectile is launched with a speed of 140 m/s at an angle of 45 degrees above the horizontal, from a height of 1500 m above the ground. How far does it travel in the horizontal direction before hitting the ground?
A baseball is struck by a batter and leaves the bat at an angle of 42° from the right horizontal and an initial velocity of 49 m/s (also known as exit velocity) at a height of 1.6m from the ground. How far has the ball traveled, horizontally, when it returns to 1.6 m above ground?
A football game begins with a kickoff in which the ball travels a horizontal distance of 37 m(approximately 40 yd) and lands at the same level from which it was kicked. If the ball waskicked at an angle of 44 ° above the horizontal, what was its initial speed?
Suppose that a shot putter can put a shot at the worldclass speed 15.00 m/s and at a height of 2.160 m.What horizontal distance would the shot travel if the launch angle is (a) 45.00° and (b) 42.00°? The answers indicate that the angle of 45°, which maximizes the range of projectile motion, does not maximize the horizontal distance when the launch and landing are at different heights.
In a game war, one team sets base on a cliff 15m high and 60m away from theopponent’s base. At what velocity must the attack be launched so that the lower basewill be hit? The initial launch is at 20 degrees below the horizontal?
In a game war, one team sets base on a cliff 15m high and 60m away from the oppenents base. At what velocity must the attack be launched so that the lower base will be hit?
