Question 146508: I am having a problem trying to solve this linear equation word problem.
Velocity of a bullet.
A gun is fired straight upward. The bullet leaves the gun at 100 feet per second (time t=0). After 2 seconds the velocity of the bullet is 36 feet per second. There is a linear equation that gives the velocity v in terms of the time t. Find the equation and find the velocity after 3 seconds.
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
you have two points on the line, (0,100) and (2,36)
the slope (m) is (36-100)/(2-0) or -32
the y-intercept (b), where x equals 0, is 100
y=mx+b __ v=-32t+100
when t=3 __ v=-32(3)+100 __ v=4
