The disturbance does not have a specific motions
Answer:
B - Velocity
Explanation:
Velocity definition: “The speed of something in a given direction.”
KE = 1/2 x 80 x 60^2
KE = 144000
Positive charge=proton
Negative charge=electron
No charge/neutral=neutron
Answer:
u = - 38.85 m/s^-1
Explanation:
given data:
acceleration = 2.10*10^4 m/s^2
time = 1.85*10^{-3} s
final velocity = 0 m/s
from equation of motion we have following relation
v = u +at
0 = u + 2.10*10^4 *1.85*10^{-3}
0 = u + (21 *1.85)
0 = u + 38.85
u = - 38.85 m/s^-1
negative sign indicate that the ball bounce in opposite directon
