8. A projectile launcher launches a snowball at 45 m/s from the top of building I as shown in the diagram. Does the snowball land on top of building 2? Support your answer with calculations. 12 m building 1 35° -150 m- -35 m- building 2 25 m

y = 25 m/s 35 -20 m 1. As a volcano erupts, one particular lava rock is projected from the mouth of the volcano at 35 degrees above the horizontal, calculate: a. The lava rock's total time in the air. b. Total horizontal distance traveled of the lava rock. c. The rock's final total velocity.

4. A ball is shot from a cannon at 50 m/s at an angle of 30° above the horizontal. a. Draw a labeled diagram with all relevant information. Note directions you chose to be +x and +y. b. How far has the ball traveled horizontally when it reaches its highest point in the flight? How high is it at this point? c. What is the speed of the ball at the highest point in its flight?

8. A car is moving north at a speed of 25 m/s. A child in the back seat of the car throws a toy to the passenger in the front seat with a speed of 10 m/s in the direction forward 50° right (relative to the car). a) Draw a vector diagram to illustrate the situation. b) Calculate the speed and direction of the toy relative to the road.

3. A baseball player throws a 145g ball toward home-plate from the out-field. The throw was made at 30.0m/s, 30.0° above horizontal [South]. If the baseball player releases the ball 2.45m above the ground; a. Determine the velocity (speed and direction) at the moment the ball strikes the 'turf (ground). b. Determine the time at which the ball possessed a minimal amount of kinetic c. Determine minimum level of kinetic energy for the ball throughout its flight. | energy.

1. According to legend, George Washington threw a silver dollar across the Potomac River, which is about 1600 m (1 mile) wide. For this problem, assume projectile motion and that the quarter was thrown at an angle of 45° and it landed at the same height it was thrown. A. How fast would he have had to throw the silver dollar to make it across the Potomac? B. Assess your answer from part a). Does this seem like a plausible feat?
