- A cannonball is launched from the top of a flat mountainside, which slopes upwards at 35 degrees with respect to the horizontal. The cannonball exits the cannon moving at 150 m/s, at an angle of 55 degrees with respect to the horizontal. a)How much time (in seconds) elapses between the moment the cannonball is fired and the moment it lands on the mountainside.b)How far down the mountainside (in meters) does the cannonball land?A rock is tossed from the top of a building at an angle of 35° above the horizontal with an initial speed of 10 m/s. The rock lands on the ground 2.7 s after it is tossed. What is the height of the building (in m)?A ball is tossed horizontally from the highest point of a 75 m building and lands 150 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw. What is the magnitude of the velocity of the ball just before it hits the ground, in meters per second?
- An archer aims at a target that is a horizontal distance 55.0 m away and 5.0 m above the ground. The archer launches her arrow from of height of 1.5 m off the ground, and the arrow hits the target. The arrow is completely horizontal after sticking to the target (i.e., the arrow was traveling horizontally just before hitting the target). What was the initial speed of the arrow, in m/s?Soccer ball is punted from the ground an an angle of theta=59 degrees with respect to the horizontal.
