If velocity is 0.2m/s, what is the kinetic energy?
Natalija [7]

\huge\boxed{♧ \: \mathfrak{ \underline{Answer} \: ♧}}

we know,

\boxed{kinetic  \:  \: energy =  \frac{1}{2} m {v}^{2} }

So,

\longmapsto \dfrac{1}{2}  \times 10 \times 0.2 \times 0.2

\longmapsto0.2 \: joules

A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 3.00 s for the
Vladimir [108]

Answer:

Initial velocity = 29.43m/s b) Height it reaches = 44.145 m

Explanation:

Using the first equation of motion we have

v=u+at

here

v is the final velocity

u is the initial velocity

a is the acceleration of the object

t is time

When the ball reaches it's highest point it's velocity will become 0 as it will travel no further

Also the acceleration in our case is acceleration due to gravity (-9.8m/s^{2}) as the ball moves in it's influence alone with '-' indicating downward direction

Thus applying the values we get

0=u-(9.81)m/s^{2}\times 3\\\\u=19.43m/s

b)

By 3rd equation of motion we have

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

here s is the distance covered

Applying the value of u that we calculated we get

s=\frac{-u^{2}}{2g}\\\\s=\frac{-29.43^{2}}{-2\times 9.81}\\\\s=44.145m
