Question

There's my problem PLEASE HELP

Answer 1

The 10 kg object has more kinetic energy

Step-by-step explanation:

Velocity is more important than mass.

Answer 2

Answer : The correct option is, the 5 kg object has more kinetic energy.

Explanation :

Formula used for kinetic energy is:

`K.E=(1)/(2)mv^2`

where,

K.E = kinetic energy

m = mass of an object

v = velocity of an object

Now we have to calculate the kinetic energy for 5 kg object with velocity 10 m/s.

`K.E=(1)/(2)* (5kg)* (10m/s)^2`

`K.E=250J`

Now we have to calculate the kinetic energy for 10 kg object with velocity 5 m/s.

`K.E=(1)/(2)* (10kg)* (5m/s)^2`

`K.E=125J`

From this we conclude that, 5 kg object with velocity 10 m/s has more kinetic energy as compared to 10 kg object with velocity 5 m/s.

Hence, the correct option is, the 5 kg object has more kinetic energy.
