Answer:
<em>15 cm</em>
<em></em>
Explanation:
Displacement is the shortest distance between the point of origin of a body in motion to the final stopping positing.
For this ant's aunt's aunt that travels from the 15.00 cm mark to the 85.00 cm mark back to the 30.00 cm mark and then finally to the 30.00 cm mark, the displacement from the starting position is..
displacement = stopping point - starting point
d = 30 cm - 15 cm = <em>15 cm</em>
Answer:
0.947 rad or 54.27 degrees
Explanation:
Suppose the collision is elastic, meaning the momentum is preserved.
Before the collision and the second ball has no momentum
Right after the collision and the first bast ball has no momentum.
Therefore momentum of the first baseball has been transferred to the 2nd ball
After the collision, the second ball would gained kinetic energy, which then would be transferred to potential energy once it reaches its highest point:
By the law of energy conservation:
By law of energy conservation:
So at its highest point, the ball is 0.562 m from the lowest point. Since the ball is hanging on a 1.35 m string, we can calculate the vertical distance from there to the swinging point:
1.35 - 0.562 = 0.788 m
Finally, the angle that string makes with the vertical at the highest point is
