a downward acceleration of 10 meters per second per second. With what velocity does the ball strike

the ground?

b) At time t = 0 months, your company has $300 million in cash on hand. Over the next 12 months,

this amount of cash is expected to change at a rate of f(t) = (6 3t) (t 8) = 3t2 + 30t 48 million

dollars per month.
