v^2 = u^2 + 2as
with v= 0, a=g, s=u^2/(-2g)
g on the moon is 1/6
u is equal, then it goes 6 times higher on the moon.

v = u + at
with v= 0, a=g, t = u/(-g)
g on the moon is 1/6
u is equal, then it takes 6 times longer on the moon.

s = vt , v is equal
t on the moon is 6 time longer
it moves 6 times farer on the moon

A worker pushes a 1080 N crate with a horizontal force of 345 N a distance of 14 m. Assume the coefficient of kinetic frictin be

amm1812

Answer:

The work done by the worker on the crate is 4830 J.

Explanation:

Given that,

Force = 1080 N

Horizontal force = 345 N

Distance d = 14 m

Coefficient of friction = 0.22

We need to calculate the work done

Using formula of work done

$W = Fd$

F = force

d = distance

Put the value into the formula

$W=345\times14$

$W=4830\ J$

Hence, The work done by the worker on the crate is 4830 J.

Answer:

D. 24.0m

Explanation:

formula

S=d/t

s=speed

d=distance

t=time

s=3.0m/s

d=x

t=8.0s

s=d/t

d=s*t

d=3.0*8.0

d=24.0m
