Explanation:
The velocity of car A relative to car B is (10km/h+40km/h)=50km/h
False: 20N downward. There are forces acting on the object.
Answer:
Explanation:
Given data
Mass m=5 kg
Moment of Inertia I=0.0648 kg.m²
Radius r=0.18 m
Linear Speed v=4.8 m/s
To find
Total Kinetic Energy K.E
Solution
The total kinetic energy K.E can be found as below
First we need to find the angular speed ω
So
Substitute the angular speed and given values to find total kinetic energy
So
