Question

the Kinetic energy of an object moving with a velocity of 10m/s is 300 joules determine the mass of the object​

Answer 1

Answer:

m= 6kg

Explanation:

Ek=300J

V=10m/s

m=?

$ek = \frac{1}{2}m {v}^{2}$

$300 = \frac{1}{2}m \times 10 \times 10$

$3 = \frac{1}{2} \times m$

$m = 3 \times 2$

$m = 6$

mass=6kg
