it is A hope it is useful.
Explanation:
Speed or velocity (V) = 35 m/s
Kinetic energy (K. E) = 1500 Joule
mass (m) = ?
We know
K.E = 1/2 * m * v²
1500 = 1/2 * m * 35²
1500 * 2 = 1225m
m = 3000 / 1225
m = 2.45 kg
The mass of the object is 2.45 kg
Hope it will help :)
My Physics teacher keeps giving us way too much work to do at home.
Electromagnetic waves do not require a medium to travel through. They can travel through empty space or matter.
