What is the velocity of a 15.0 kg mass if its kinetic energy is 3.50 x 103 J? a. 467 m/s b. 0.0926 m/s c. 21.6 m/s d. 2.17 x 105 m/s

We are Given:

Mass (m) = 15 kg

KE = 3.5 * 10³ J

Velocity (v) = v m/s

Solving for the Velocity:

We know that:  KE=  1/2 mv²

replacing the variables

3.5 * 10 = 7.5 * v²

v² = 3.5 * 10³/ 7.5

v² = 466.67

v = √466.67

v = 21.6 m/s

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

i believe it is b. what was the cause of the big bang

hope this !
