2013 indianapolis 500 champion tony kanaan holds his hand out of his indycar while driving through still air with standard atmospheric conditions. (a) for safety, the pit lane speed limit is 60 mph. at this speed, what is the maximum pressure on his hand? (b) back on the race track, what is the maximum pressure when he is driving his indycar at 225 mph? (c) on the straightaways, the indycar reaches speeds in excess of 235 mph. for this speed, is your solution method for parts (a and (b) reasonable? explain.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

You throw a baseball directly upward at time =0 at an initial speed of 14.9 m/s. what is the maximum height the ball reaches above where it leaves your hand? ignore air resistance and take =9.80 m/s2.

Global climatic patterns are changing because of the melting of polar ice caps. the melting of polar ice caps is an example of the interaction between the atmosphere and cryosphere cryosphere and geosphere hydrosphere and geosphere biosphere and cryosphere
