Answer:
Yes it would be different on Earth and the moon
Answer:
A
Explanation:
Constant speed (without change in direction) is not accelerating. If you are slowing down, speeding up, or changing direction, you are accelerating
Answer:
You are a guest magician in a circus. One of your tricks is to place a football on an inclined plane without the football rolling over is explained below in details.
Explanation:
spinning ball halts after traveling some range due to friction energy act different direction of movement of the ball. you can observe in the figure.
Let any rolling ball of mass (m ) is traveling with velocity v ,
common effect on ball (N) = mg
because of motion, friction energy develops on the contact exterior and begins to resist the movement of the rolling ball.
hence,
fr = uN = umg act on communicating exterior, so, after any time due to friction energy rolling ball gets to rest.
The answer is 294j by puting it in kinetic energy formula.
