Question

What is the kinetic energy of a block with a mass of 10 kilograms traveling at a speed of 12 m/s ? Ignore friction

Answer 1

solution

here,

mass(m)=10kg

speed(v)=12m/s

now,

kinetic energy=1/2mv^2

=1/2 x 10 x (12)^2

=720J

Step-by-step explanation:

Answer 2

Kinetic energy is 720 Joules

Step-by-step explanation:

`{ \rm{kinetic \: energy = (1)/(2) m {v}^(2) }}`

• m is mass
• v is velocity

`{ \tt{k.e = (1)/(2) * 10 * 12 {}^(2) }} \\ \\ { \tt{k.e = 720 \: joules}}`
