Answer: 4 kg
Explanation:
Ke=1/2MV^2
plug in the kinectic energy and solve for M
50=1/2(M) (5^2)
M= 4
Answer:
Explanation:
This is a simple F = ma equation. We have the mass and we have the acceleration, so
F = 1298(17) and
F = 22066 which rounds correctly to
F = 22000N
I believe the correct answer is true. <span>A machine can make doing work easier by reducing the force exerted, changing the distance over which the force is exerted, or changing the direction of the force. Hope this answer the question.</span>
The zeroth law of thermodynamics states that if two thermodynamic systems each are in thermal equilibrium with a third, then they are in thermal equilibrium with each other.
