Question

.A car is travelling at a velocity of 10 m/s and it has a mass of 250 Kg. What is its Kinetic

energy?​

Answer 1

${\boxed{\underline{ \orange{\tt{Required \: \: answer:-}}}}}$

★GIVEN :-

• Mass = 250kg

• Velocity = 10m/sec

★TO FIND :-

• Kinetic Energy

★FORMULA USED:-

• $\displaystyle \sf{K. E. = \frac{1}{2} m {v}^{2} }$

★SOLUTION:-

This is a quite basic question:-

Taking the values in the formula,

$: \longrightarrow \displaystyle \sf{ K. E. = \frac{1}{2} \times 250kg \times {10 \frac{m}{sec} }^{2} }$

$: \longrightarrow \displaystyle \sf{ K. E. = \frac{1}{ \cancel{2}} \times 250 kg\times \cancel{100 } \frac{ {m}^{2} }{ {sec}^{2} } }$

$: \longrightarrow \displaystyle \sf{ K. E. = 250 \times 50 \: kg. \frac{ {m}^{2} }{ {sec}^{2} } }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \boxed{ \underline{ \displaystyle{ \rm{ \purple{ K. E. = 12500 \: joule}}}}}}$

Answer 2

12500 joule
