Question

The roof of a two-story house makes an angle of 25 with the horizontal. A ball rolling down the roof rolls off the edge at a
speed of 5.3 m/s. The distance to the ground from that point is 5.9 m.
For how much time t is the ball in the air?
What is the distance d from the base of the house to where
the ball lands?
What is the x component of its velocity V, just
before landing?

A projectile is fired with an initial speed of 32 m/s at an angle 65° above the horizontal. The object hits the ground 8.5 seconds later. Using 9.80 m/s2 for the local acceleration due to gravity, how much higher or lower (in m) is the launch point relative to the point where the projectile hits the ground? To what maximum height (in m) above the launch point does the projectile rise? What is the magnitude of the projectile's velocity when it hits the ground? What is the angle (in deg) of the projectile's velocity below the horizontal when it hits the ground?

A small boat sailed straight north out of a harbor in strong east wind (blowing from west to east). After sailing for 120 minutes, it ended up hitting a buoy 60° to the north-east of the harbor. If the straight-line distance between the buoy and the harbor is 3 km, what is the speed of the east wind? Pick the correct answer O O O O 13. m/s 0.42 m/s 0.50 m/s 0.21 m/s 0.36 m/s East Wind ttt Harbor
Some children are practicing baseball and accidentally throw a ball onto the roof of one of their houses. Suppose that the baseball was thrown at an angle of 51° above the horizontal at a speed of 25 m/s. The ball rises to its maximum height before falling onto the roof of the house 3.6 m above the level at which it was thrown.a. determine the total time, in seconds, the baseball spends in the airb.calculate the distance in meters,between the baseball's launch point and its landing point
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.745 m above his mouth. a. What is the minimum speed at which the archer fish must spit? answer in m/s b. What angle (in degrees) above the horizontal must he spit? answer in degrees

A canon was launched with an initial speed of 104 m/s at an angle of 41.1° above the horizontal. The canon hit the top of a building that is 961 m away from where the canon was launched. What is the height of the building? 238.47 m 419.17 m 101.56 m 538.50 m
A secret agent skis off a slope inclined at θ = 28.3 degrees below horizontal at a speed of v0 = 17.4 m/s. He must clear a gorge, and the slope on the other side of the gorge is h = 11.9 m below the edge of the upper slope. a.)What is the maximum width, w, of the gorge (in meters) so that the agent clears it?
ment Chapter 04, Problem 039 Your answer is partially correct. Try again. In the figure, a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 1.80 s later, at distanced = 26.0 m from the building and at angle 0 = 56.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown (positive angle for above horizontal, negative for below)?
