Question

✦✧✧ Question ✧✧✦ ➠ ᴅᴏɴᴛ sᴘᴀᴍ⚠️ The kinetic energy of an object of mass m, moving with a velocity of 5 m/s is 25 J. What will be its kinetic energy when its speed is doubled? it is given here doubled not tripled​

Answer 1

Answer:

Hence, kinetic energy = 25 × 4 = 100 J.

If the value is increased 2 times

=25 x 4 = 100 J

plz report :)

hope it helps u keep smiling :)

Bhaiya missed u how are u

Happy rakdhabandan

Answer 2

Answer:

$kinetic \: energy \: \: \: e = \frac{1}{2} {mv}^{2} \\ e \: \alpha \: {v}^{2} \: \\ if \: velocity \: is \: doubled \: the \: \\ kinetic \: energy \: becomes \: 4 \: times \\ kinetic \: energy \: = \: 25 \times 4 = 100j$

Hope its correct!!
