A newspaper boy throws papers sideways onto the porches of his customers while riding his bicycle along the sidewalk. The sidewalk is 15 m in front of the porches. The boy throws the papers at the horizontal speed of 6.0 m/s relative to himself, and rides the bieycie at a speed of 4.0 m/s relative to the sidewalk. (a) With what horizontal speed do the papers actually travel relative to the ground? (b) How far in advance of a porch should the boy throw a paper, so that it lands on target? (c) If he waits until he is directly opposite a porch, at what horizontal angle with respect to the sidewalk will he have to throw the paper, to hit the porch?

- I am working on a problem that asks me to find out the acceleration of an object on a ramp, and I have drawn the first image. From it we could clearly see that a = g * sin (theta). But that formula does not work for all a-> because, as shown in the second image when a is larger, it is not a right triangle, so we cannot take a = g * sin (theta) to find a in this example, am I right?arrow_forwardTwo students are on a balcony a distance h above the street.
