While john is traveling along an interstate highway, he notices a 150 mi marker as he passes through town. later john passes a 112 mi marker. what is the distance between town and john’s current location? answer in units of mi. 003 (part 2 of 2) 10.0 points what is john’s current position?

Part a)

distance = 112 miles

Part b)

current position = 112 miles from the position of town

Explanation:

Part a)

Since the distance marker is showing the distance between the town and the position of john at all time

so here we have

Part b)

Current position of John is given as

from the position of the town

a) When John is in the town (and suppose that he is travelling in a straigth line), he sees a 150 mi marker (means that he is 150 mi away from somewhere, let's suppose is a city), and latter, he sees a 112 mi marker (so he is now 112mi from the city) this means that he is closer to the city, and further to the town, then, the distance between john and the town will be 150 mi - 112 mi = 38 mi

b) currently, john is 38 mi ahead of the town and 112 mi away from the city.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
