Inelastic, because the ball 'glued' to the girl, so she has the same quantity of movement as the ball
The answer is 1.9 m
The ideal mechanical advantage (IMA) is the ratio of input distance (ID) to output distance (OD):
IMA = ID/OD
IMA = 2
ID = ramp length = 3.8 m
OD = height = ?
2 = 3.8m/OD
OD = 3.8/2
OD = 1.9 m
Answer:
confirmation bias
Explanation:
