Cheri has a new Dodge Charger with a Hemi engine and has challenged Vince, who owns a tuned VW GTI, to a race at a local track. Vince knows that Cheri’s Charger is rated to go from 0 to 60 mph in 5.3 s, whereas his VW needs 7 s. Vince asks for a head start and Cheri agrees to give him exactly 1 s. (a) How far down the track is Vince before Cheri gets to start the race? (b) At what time does Cheri catch Vince? (c) How far away from the start are they when this happens? (Assume constant acceleration for each car during the race.)

a) 1.915 s

b) 7 s

c) 122.5 m

Explanation:

1 mph = 0.44704 m/s

60 mph = (0.44704 * 60) m/s = 26.8 m/s

a) The VW acceleration = = (26.8 m/s - 0 m/s) / 7 s =  3.83 m/s²

Cheri's acceleration = = (26.8 m/s - 0 m/s) / 5.3 s = 5 m/s²

The distance traveled is given as:

b) The distance traveled by Vince VW with a 1s head start is given as:

The distance traveled by Cheri is given as:

c)

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
