Answer:
0 m/s
Explanation:
Relative speed is defined as the speed of an object with respect with another object.
In other words, it is the speed of an object as viewed from the frame of reference of another object.
When two objects are moving in the same direction, their relative velocity is given as:
where velocity of first object
velocity of second object
In the case of the two cars,
22 m/s
Therefore:
Their relative velocity is 0 m/s.
Answer:Given mass = 4.1kg
Radius = 0.0117m
Velocity V = 8.4m/s
Coefficient of friction = 0.25
Explanation: Below is an attached solution to the problem stated above.
1. The angular acceleration is equal to 524rad/s^2
2. The linear acceleration is equal to 2.45m/s^2
3.the time it takes the ball to begin rolling = 0.98s
4. The distance the ball slides before it begins to roll = 7.05m
