Projectile Motion Name Post-Lab Quiz 1. Using your results from table 1, calculate the time of flight, t 2. Investigating an accident scene, you are asked whether or not a wrecked car was speeding before it crashed straight from a bridge with no rail into the Ohio River below. The bridge height is 4.00 meters, and the car landed 15.0 meters horizontally from the point it left the bridge. The posted speed limit on the bridge is 25 mph, or about 11.2 m/s. Was the car speeding? Show your work. 3. Using your data from table 2 calculate the max height, ymax, and the time of flight to reach the max height, tmaxs, for angles of 30°, 45°, and 60°. Use the following table for your results, show an example of your calculations and comment on the results. 45 60 max tmax Refer to your Range versus Angle graph. What angle corresponds to the maximum range? Why isn't the graph exactly symmetric about 450? From your curve fit equation. calculate the range for an angle of projection of 10° 4. 5. Rather than getting out of bed, you decide to toss a shoe at your alarm clock to shut it off Being a conscientious physies student, you decide to calculate the velocity with which you must lob the shoe, at an angle of 60.0 degrees, in order for it to hit your clock. The clock is 1.50 meters away on your dresser top which is at about the same height where you toss the shoe from. What is the velocity needed for this task?Explanation / Answer
2.
Considering motion to be vertical
R= ut
15= ut (i)
Considering motion along vertical
Y= 0.5gt^2
4= 0.5*9.8*t^2
t= 0.9035 s
Putting in (i)
u= 16.6 m/s
Yes the car was speeding up
