( b ) An object of mass 24 kg is at a certain height above the ground . If the potential energy of the object is 960 J , find the height at which the object is with respect to the ground . Given , g = 10 ms .

$\huge\rm\red{❥AnsWer}$

$\rm\blue{❥given}$

• mass of the object is 24kg

• potential energy is 960 J

• g = 10ms

$\rm\blue{❥To\:find}$

• height of the object .

By using the formula .

$\rm\green{P.E = mgh}$

• here P.E is potential energy

• m is mass

• g is acceleration due to gravity

• h is height .

Put the value

960 = 24 × 10 × h

960 = 240 × h

h = 960 /240

h = 4 m

Therefore height is 4 m

Answer 2

$\bold{\large{\boxed{\red{\tt{ANSWER}}}}}$

$\purple{Given:-}$

☆ Mass of the object = m = 24 kg

☆ Acceleration due to gravity = g = 10 m/s^2

☆ Potential energy = 960 J

We need to find the height (h)

We know that ,

$\bold{\large{\boxed{\blue{\tt{Potential \: energy = m × g × h }}}}}</p><p>$

$\rightarrow{\tt{960 = 24 \times 10 \times h}}$

$\rightarrow{\tt{h = \frac{960}{24 \times 10} }}$

$\rightarrow{\tt{h \: = \frac{96}{24} }}$

$\rightarrow{\tt{h = 4 \: m}}$

$\tt{So \: the \: object \: is \: at \: 4 \: m \: height}$

I hope it helps u dear friend ^_^
