A catapult is tested by Roman legionnaires. They tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): Range = 0.20 km; angle of launch = /4; landing height = launch height.
What is the initial velocity of launch of the boulders if air resistance is negligible? A) 44 m/s
B) 1.4 m/s
C) 22 m/s
D) 0.69 m/s
Question 2
A 2.0 F capacitor is charged to 12. V and then discharged through 4 106 . How long will it take for the voltage across the capacitor to drop to 3.0 V?
What will be an ideal response?
