Question

motor bike at a speed of 12 metre per second has a kinetic energy of 3600J determine its mass​

Answer 1

QUESTION-:

motor bike at a speed of 12 m/s has a kinetic energy of 3600J determine its mass​

EXPLANATION-:

• Kinetic energy(K.E)= 3600 J
• Speed (v)=12 m/s
• Mass=(m)=??

We know that-:

$\longrightarrow \dag\red \underline{ \boxed{\rm\;K.E=\frac{1}{2}mv^2}}\dag$

Where-:

K.E is Kinetic energy

m is mass of the body

v is velocity of body

Putting values in the formula-:

$\rightarrow \bf\; 3600=\frac{1}{2}m(12)^2\\\\\rightarrow \bf\; 3600=\frac{1}{2}\times m\times144\\\\\rightarrow \bf\; 3600=72m\\\\\rightarrow \bf\; m=\frac{3600}{72}\\\\\implies \bf\; \bigstar \underline{\boxed{\sf\; m=50\;kg}}\bigstar$

∴ The mass of body is 50 kg
