A balloon, considered spherical, is 30 ft in diameter. The surrounding air is at 81 °F and the barometer reads 30.65 in Hg. What gross load may the balloon lift if it is filled with a) hydrogen at 112 °F and atmospheric pressure. b) helium at 112 °F and atmospheric pressure? C)Helium is nearly twice as heavy as hydrogen. Does it have half the lifting force of hydrogen?

A. How fast was the motorcycle at 5s, 10s, 15s, 20s?
B Solve the acceleration through the following time intervals: 0 to 5s, 5s to 10s, 10s to 15s, 15s
to 20s?
Your answer in A should be: 30km/h, 50km/h, 80km/h,100km/h (in order)
Your answer in B should be : (21,600km/h?), (14,400km/h?), (21,600km/h?),(14,400km/h?)
