Question

4 A student measures the time t for a ball to fall from rest through a vertical distance h. Knowing that
the equation h =
 gt2 applies, the student plots the graph shown.
Which of the following is an explanation for the intercept on the t axis?
A Air resistance has not been taken into account for larger values of h.
B There is a constant delay between starting the timer and releasing the ball.
C There is an error in the timer that consistently makes it run fast.
D The student should have plotted h against t 2.

Answer 1

what is on the y axis

Answer 2

root h

Answer 3

Id say C

Answer 4

It is C because of systematic error?

Answer 5

when root h is 0, there is still time
This makes no sense because if there was no distance to fall, then it should take no time falling
There must be an error with the timer

Answer 6

Hm nvm B

Answer 7

then, why cant it be B then?

Answer 8

B makes more sense, "consistently making it run fast" makes no sense

Answer 9

how?

Answer 10

If it made it run faster then the slope would be steeper

Answer 11

I guess it is C becaue since the timer is running faster.

Answer 12

Is the answer C?

Answer 13

If the timer was normal then the graph would be
