Abbreviations:
T= Time
Vf = Final Velocity
Vo = Initial Velocity
Δx = Displacement (aka distance)
| … | = Absolute Value
Here is 1 Equation for Time
T= (Vf/a) - (Vo/a)
T= | (0/-9.81) - (2.78/-9.81) |
T = 0.283
Time up is the same as time down so multiply by 2.
0.283 * 2 = 0.57
Here is 1 Equation for Displacement
Δx = 0.5 * t^2 * a
Δx = | 0.5 * 0.57^2 * -9.81 |
Δx = 1.58
Answer:
Option C
1.58

Answer:
t=1/4v1
Explanation:
Given data
Car one
Speed =v1
Time =t
Distance =1/4 mile
Given data
Car two
Speed =v1/2
Time =t
Distance =d
Speed =distance/time
v1=1/4/t
v1t=1/4
t=1/4*1/v1
t=1/4v1 seconds
