Question

instantaneous velocity of a body is 10m/ s . if it has an acceleration of 2.0 m/s , how much velocity will it aquire after traveling 11

?

Answer 1

Given,

Initial Velocity (u) = 10m/sec

Acceleration (a) = 2m/sec²

Distance travelled (s) = 11m

Final Velocity (v) = ?

Using Third equation of motion.

v² = u² + 2as

v² = 10² + 2*2*11

v² = 100 + 44

v² = 144

v = 12m/sec
