Arunner accelerates to a velocity of 5.36 m/s due west in 3.00 seconds. his average acceleration is 0.640 m/s2 also directed due west. what was his velocity when he began accelerating?

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.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
