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

Question 9: A stone is thrown off of a bridge that is 40m above the water. The stone lands 48m from the base of the bridge. The stone was thrown with an initial velocity of 15m/s at 30 degrees above the horizontal. a) What are the initial position coordinates of the stone? b) What are the components of the initial velocity? (Answer: 13m/s, 7.5m/s) c) What is the maximum height the stone reaches above the water? (Answer:...

Hector and Javier are standing on a bridge 50m above a river. Hector throws a stone down with a speed of 20 m / s. Javier, at exactly the same time. Ignore air resistance. a) How much time elapses between the first hit and the second of the stones in the water? b) Which stone has the highest speed when it hits the water?

A suspension bridge is 62.0 m above the level base of a gorge. A stone is thrown or dropped from the bridge. At the location of the bridge, g has been measured to be 9.83 m/s2. In each of the following, assume that there is no air resistance. (a) If you drop the stone, how long does it take for it to fall to the base of the gorge? s (b) If you throw the stone straight down with a...

A stone is dropped from a bridge that is 18.0 m above a stream. A piece of driftwood floating down the stream is at a distance of 2.26 m from the bridge when the stone is released. If the stone lands on the wood, what is the speed of the stream? Another stone is thrown straight up from the bridge with an initial speed of 3.00 m/s. It just misses the edge of the bridge on the way down and...

NAME: Problem 1. (40 pts) A stone is dropped into a river from a bridge that i ove the water (with zero initial velocity). Another stone is thrown at an angle of 45° below the horizontal exactly 1 (one) second after the first with some initial velocity. As it turns out the two stones hit the water at exactly the same moment. (Hint: after means shorter time.) a) (20 pts) What is the initial velocity of the second stone? b)...

(4 points) A stone is thrown from a rooftop at time t=0 seconds. Its position at time t is given by r(t) = 4ti — 2tj + (24.5 – 4.912) k. The origin is at the base of the building, which is standing on flat ground. Distance is measured in meters. The vector i points east, j points north, and k points up. (a) How high is the rooftop? meters. (b) When does the stone hit the ground? seconds. (the...
