Suppose a ball is dropped from the roof of a tall building, 290 m above the ground. The distance the ball falls after t seconds, ignoring air resistance, is given by d(t)=4.9t^2 (a) Fill in the table below, correct to 2 decimal places.

(b) From your answers in part (a), what does the instantaneous velocity at t=2 s appear to be?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

for future students the answer is b
