C. Force causes displacement
Answer:
height is 4 times
Explanation:
speed of ball hit by Luis is u
speed of ball hit by Ron is 2u
Let the maximum height traveled by the ball hit by Luis is h and by the ball hit by Ron is h'
At maximum height, the final velocity of ball is zero in both the cases.
Use third equation of motion, we get
For Luis :
.... (1)
For Ron :
.... (2)
Divide equation (2) by equation (1), we get
h' = 4 h
Thus, the statement of third student is wrong.
Answer:
About 6.26m/s
Explanation:
Divide both sides by mass:
Since the point of equality of kinetic and potential energy will be halfway down the cliff, height will be 4/2=2 meters.
Hope this helps!
The correct answer is *mechanical advantage*
Heat, gravitational pull, amount of gas and what type of gas in the air.
