vf^2=vi^2+2ad
50^2=10^2 + 2 a 60
solve for a.
then, vf=vi+at solve for time t.
A car travelling with constant acceleration increases its speed from 10 m/s to 50 m/s over a distance of 60 m . how long does this take?
a. 2 seconds b. 4 seconds .
Data :
Avg Velocity = 10 + 50 / 2 = 30m/s
Distance = 60 meter
time = ?
Solution :
S= V x T
making "T" subject . Then
T= S/V
T= 60/30
T = 2 seconds . This Answer is correct , but please tell me that the way I have solved this is correct or not? Thanks
