Question

JUST CHECK MY ANSWER:

Answer 1

A radar gun was used to record the speed of a runner (in meters per second) during selected times in the first 2 seconds of a race. Use a trapezoidal sum with 4 intervals to estimate the distance the runner covered during those 2 seconds. Give a 2 decimal place answer and include units.

t 0 0.5 1.2 1.5 2
v(t) 0 4.5 7.8 8.3 9.0

Answer 2

My answer:
(b-a)/n
(b-a)/n = (2-0)/4 = 0.5
0.5/2=0.25
0+(2*4.5)+(2*7.8)+(2*8.3)+9.0
0+9+15.6+16.6+9
50.2
50.2(0.25)=
12.55
