Question

1 kg mass has kinetic energy of 2 joule calculate its velocity

Answer 1

Explanation:

kE = 1/2 mv²

2 = 1/2 × 1 × v²

V= 1m/s

Answer 2

b is equal to root over 2. kinetic energy is equal to 2. kinetic energy is also equal to half MV square. since mass is 1 kg, so v is equal to root over 2.
