A. Move 2 m east and then 12 m east; displacement is 14 m east and the distance is 14 m
B. Move 10 m east and then 12 m west, the displacement is 2 m west and the distance is 22 m.
C. Move 8 m west and then 16 m east; the displacement is 8 m east and the distance is 24 m
D. Move 12 m west and then 8 m east; the displacement is 4 m and the distance is 20 m
Answer:
The starting velocity for ball 1 is 1.00 meter/second. Its ending velocity is 0.25 meter/second.
The change in velocity for ball 1 is 0.25 – 1.00 = -0.75 meter/seconds
Answer:
D. A lower Voltage into a higher
Answer:
4.69 s
Explanation:
u = Initial velocity = 30 m/s
= Angle of launch = 
g = Acceleration due to gravity = 
Time taken by the projectile to land is given by
The time the projectile is in the air before it contacts the ground again is 4.69 s.
