Question:
A car is initially 4.0km/h south of a gas station and is moving at a constant speed of 55km/h due north. A truck is initially 6.0km north of the gas station and is moving at a constant speed of 45km/h due south. How far are the vehicles from the gas station when they pass each other...
I am currently in high school and am decided what career to pursue. I shadowed a medical physicist for a day and found it to be quite interesting. After doing more research I discovered that usually an undergraduate degree in physics is needed to pursue further studies in med phys. I am taking...
Got the answer!
1.4m=vi(0.20)+1/2(-9.81)(0.20)^2
1.4m=vi(0.20)-0.1962
1.5962=vi0.20
vi=7.981 m/s
then plugging it back in
d=vi(t)+1/2at^2
d=7.981(0.20)+1/2(9.81)(0.20)^2
d=1.7924
d=1.8m
thanks for the help :)
I am still a bit confused with the x's u are using in your formula. We were given the formula
d=vi(t) + 1/2at^2
how did u get all of those x's into it and 0's for the x's
thanks for all the help!
car 1-
vi=0 m/s
a=5.00 m/s^2
Truck
v=25.0 m/s
assuming the distances are the same at the beginning
distance would equal zero as they are stopped
using the formula d=Vi(t)+1/2at^2
0=0t+1/2(5.00)t^2
0=1/2(5.00)t^2
0=5.00t^2
0=t^2
t=0
plug that back into the formula...

Homework Statement
A car is waiting at a stoplight. Just as the light turns green and the car starts to accelerate, a truck passes at a constant velocity in the next lane. The truck passes at a velocity 25.0 m/s while the car accelerates 5.00 m/s^2 both in the same direction,
