Answer:The tangential acceleration is 0 m/s².
Explanation:Given:
Radius of the wheel = 0.5 m
The point of observation for calculating tangential acceleration = 0.2 m from center.
Tangential speed at the point of observation = 2 m/s
The angular speed of the wheel is a constant.
In order to determine the tangential acceleration, we make use of the following formula:
Tangential acceleration at a point = Angular acceleration × Distance of the point from center
Or, a_t=\alpha \times r
Now, angular acceleration is defined as the rate of change of angular speed.
Here, the angular speed of the wheel is a constant. So, the change of angular speed is 0. Therefore, the angular acceleration is also 0 rad/s².
Now, from the above formula, as angular acceleration is 0, the magnitude of tangential acceleration at a point that is 0.2 m from the center of the wheel is also 0 m/s².
Hope it helped
It will change the way we do normal things such as going to certain stores, have arrows showing what lane you can go down, not being able to leave the country for awhile, and social interaction
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
Initial velocity of
Initial velocity of (opposite direction)
Final velocity of (same direction )
Final velocity of (same direction)
v = 0.5 m/s

The speed of the carts after their collision is 0.5 m/s.
