Derivation of Velocity-Time Relation by Graphical Method

SOLVE- A car ...

Question

SOLVE- A car starts from rest and achieve a speed of 36 km/hr with uniform acceleration of 1.5 m/s². Find time taken by it.?

Open in App

Solution

given u = 0 m/s
v = 36 km/hr = 36*5/18= 10 m/s
a = 1.5 m/s²
t = ?
Since, v = u + at
v - u /a = t
t = (10 - 0)/ 1.5 = 6.67 s
