The Joule is a unit of energy, not Force
Answer:
t=1.87s
b. 9.74
Explanation:
First to find time set an equation for angular velocity:
Now to find the angle:
Answer:
Speed is 1.962*10^-3m/s
Explanation:
Given that
Mass of proton==1.67*10^-27
Acceleration due to gravity (g)=9.81m/s^2
Angle of inclination A=90°
Charge (q)=1.6*10^-19
Magnetic field (B)=5*10^-5T
From lorentz force
It can be seen that
F=w =mg=qvBsinA
We're Velocity (v)=mg /qBsinA
V=1.67*10-27*9.81/1.6*10^-19*5*10^-5*sin90
V=1.962*10^-3m/s
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
Either one is fun and great to play!
