1. Why do tires grip the road better on level ground than they do going uphill or downhill?
I have some ideas, but I'm not sure how to word them, or if they are correct. Any suggestions would be appreciated.
2. A mass M(1) = 3.5 kg, rests on a horizontal table and is attached by ropes to masses M(2) = 1.5 kg and M(3) = 2.5 kg. After is is released, what are the magnitude and direction of the acceleration of M(1)? Ignore friction.
Answer: I calculated 1.14 m/s^2 to the right. The answer is known to be between 1-2. If anyone can confirm my calculation it would be appreciated.
~Thanks.
