You said 0.5 · m · v² = m · g · h

Divide each side by 'm' :  0.5 · v² = g · h

Multiply each side by 2 :  v² = 2 · g · h

Square root each side :   v = √(2 · g · h)

You said that  g = 9.8 m/s²  and  h = 875 units

So  v = √(9.8 m/s² · 875 units)

v = √(8,575 m·unit/s²)

v = 92.6 / s² · √(m · unit)

A force of 100.0N is appliesd to an object of mass 85.0kg. what is the object acceleration
kumpel [21]

Answer:

<h2>1.18 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{100}{85}  =  \frac{20}{17}  \\  = 1.176470...

We have the final answer as

<h3>1.18 m/s²</h3>
