Hi!
givens: initial velocity = 0 m/s
time = 8.5 s
acceleration = 10 m/s^2
Unknown: displacement, velocity final
Equation:
Displacement = 1/2 (at^2) + viT
SS:
Displacement = 1/2 (10 * 8.5^2) + 0
Displacement = 361.25 m in a positive direction.
My math might be a little off, but I'm not sure...
But yeah! Hope this helped :)
Answer:
kilograms and grams
Explanation:
kilograms is the stadard unit for mass according to the SI system.
Grams is another unit for mass.
Answer:
The velocity with which the mass will hit the floor is 
Explanation:
If the tension in the string is
, for
we have
,
and for the mass

From these equations we solve for
and get:

The kinematic equation

gives the final velocity
of a particle, when its initial velocity was
, and has traveled a distance
while undergoing acceleration
.
In our case
(the initial velocity of the particles is zero)

which gives us



which is the velocity with which the mass
will hit the floor.
