Answer:
Acceleration of gravity on Noveria = 4.4 m/s²
Explanation:
Commander Shepard, an N7 spectre for Earth, weighs 799 N on the Earth's surface.
We have weight, W = mg
Acceleration due to gravity, g = 9.81m/s²
799 = m x 9.81
Mass of Shepard, m = 81.45 kg
She lands on Noveria, a distant planet in our galaxy, she weighs 356 N.
We have weight, W = mg'
356 = 81.45 xg'
Acceleration of gravity on Noveria, g' = 4.4 m/s²
Answer:If the object's speed increases.
Explanation:
If the object's speed increases, then its kinetic energy will increase. If the kinetic energy increases, the change in kinetic energy will be positive.
Choice A is correct.======Kinetic energy equation: KE = (1/2)(m)(v²)This tells us that KE is directly proportional to mass and the square of velocity. In other words, the more mass and more velocity an object has, the more kinetic energy.If an object is sitting at the top of a ramp, there is no velocity and therefore no kinetic energy. Choices B and D are wrong.A golf ball has more mass than a ping-pong ball, so a ping-pong ball would have less kinetic energy than a golf ball rolling off the end of a ramp. Choice C is wrong.Choice A is correct.
