Answer: 6.21 m/s opposite to Janet
Explanation:
Given
mass of Janet
mass of Sarah
The initial velocity of Janet
The final velocity of Janet after the collision is
the final velocity of Sarah after the collision is
Conserving linear momentum
Negative indicates the direction of velocity is opposite than of Janet
Answer:
110 mL
Explanation:
Ideal gas law:
PV = nRT
Assuming the container isn't rigid, and the pressure is constant, then:
V/T = V/T
Plug in values (remember to use absolute temperature).
V / 293 K = 150 mL / 393 K
V = 110 mL
Answer:
Explanation:
Given,
initial angular speed, ω = 3,700 rev/min
=
final angular speed = 0 rad/s
Number of time it rotates= 46 times
angular displacement, θ = 2π x 46 = 92 π
Angular acceleration
