Question

A 1kg mass has a kinetic energy of 1joule what its velocity

Answer 1

Answer:

√2 m/s

Step-by-step explanation:

KE = 1 JOULE

m = 1 kg

we know ,

    KE = 1/2 ×m ×v²

after solving this ,

v = √2 m/s

THANK YOU .

Answer 2

Answer:

● When it's speed is 1.4m/s

=> $K.E = 1/2 m {v}^2$

=> $1 = 1/2 × 1 × {v}^2$

=> $2 = {v}^2$

=> ${v}^2 = 2$

=> $v = √2$

or

=> $1.4m/s$
