First figure shows the object position
Second shows the image position
Third shows the focal length.
A. 60 miles
B. 5 hours
Unless you are looking for slope, in which case the answer is different
Instantaneous velocity is the velocity at a specific instant in time. I bet you are taking Honors Physics.
For this problem, we use the derived equations for rectilinear motion at constant acceleration. The equations used for this problem are:
a = (v - v₀)/t
2ax = v² - v₀²
where
a is the acceleration
x is the distance
v is the final velocity
v₀ is the initial velocity
t is the time
The solution is as follows;
a = (60mph - 30 mph)/(3 s * 1 h/3600 s)
a = 36,000 mph²
2(36,000 mph²)(x) = 60² - 30²
Solving for x,
x = 0.0375 miles
