Arunner accelerates to a velocity of 4.15m/s due west in 1.50 s. his average accelerates is 640m/s×s also directed due west. what was his velocity when he began accelerating

Explanation:

Given, acceleration of the runner, a = 0.640 m/s²

Final velocity of the runner, v = 5.36 m/s

Time, t = 3 s

Let the velocity of the runner be u when he began accelerating.

Using the first equation of motion,

v=u+at

Substituting the values we get,

=3.44 m/s

The velocity of the runner when he began accelerating is 3.44 m/s.

this is poiselle's equation from fluid mechanic in physics. mech eng
