Answer:

v=16.234m/s

Explanation:

Given data

Distance S=6.10 m

Initial Speed u=12.0 m/s

To find

Final Speed v

Solution

From third equation of motion we know that:

v^{2}-u^{2}=2aS

where

v is final velocity

u is initial velocity

a is acceleration

S is distance

Substitute the given values to find v

v^{2}=u^{2}+2aS\\v^{2}=(12.0m/s)^{2} +2(9.8m/s^{2} )(6.10m)\\v^{2}=263.56\\  v=\sqrt{263.56}\\ v=16.234m/s

A car is moving 5.82M/S when it accelerates at 2.35M/S^2for 3.25S. What is its final velocity?
rodikova [14]

Answer:

Explanation:

vf=vi+at

vi=5.82 m/s

a=2.35 m/s2

t=3.25 s

vf=5.82+2.35*3.25

vf=5.82+7.64

vf=13.46
