A stone is dropped into a river from a bridge 42.2 m above the water. Another stone is thrown vertically down 1.70 s after the first is dropped. Both stones strike the water at the same time. What is the initial speed of the second stone? Number Units the tolerance is +/-29
45 (2 pts) A stone thrown off a bridge 20 m above a river has an initial velocity of 12 m/s at an angle of 45 o above the horizontal, as shown in Figure. a. What is the range R of the stone? b. Find magnitude and direction of the velocity of the stone when it strikes the water. (ANS. to 4 significant digits.) Range R- Magnitude: m/s Direction: deg 45 20m
Student Id # Question A stone thrown off a bridge 20 m above a river has an initial velocity 5 m/sec of at an angle of 30 degrees above the horizontal as shown in the figure. Find the location (x.y) of the stone after 1 second? What is the velocity (V1, and V1,) after 1 second? It will take T seconds to hit the water, what is T? What is the velocity (V2, and V2,) when it hits the water?...
