Mr. Billante is notorious for his road rage. After being cut off he accelerates at a rate of
+12.3 m/s2 for +455 m. As he approaches
the man who cut him off his final velocity is a
ludicrous +125 m/s. What was his initial
velocity?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Which are true about beta reactions? there will be more than one answer. a. it has no change b. it doesn't change the mass of the number c. it has a mass of 0.0005 atoms d. it causes transmutation.
