As a projectile thrown upward moves in its parabolic path, at what point along its path are the velocity and acceleration vector
1 answer:
Answer: Maximum height
Explanation:
Suppose a projectile is thrown at an angle of with velocity u
As the projectile moves upward, its vertical component of velocity decreases due to gravity. While the horizontal component remains the same as there is no acceleration in the horizontal direction.
At maximum height vertical component of velocity is zero. At this instant horizontal component of velocity is perpendicular to the acceleration due to gravity. This can be explained with the diagram.

The value of tangential acceleration 40
The value of radial acceleration
Explanation:
Angular acceleration = 50
Radius of the disk = 0.8 m
Angular velocity = 10
We know that tangential acceleration is given by the formula
Where r = radius of the disk
= angular acceleration
⇒ 0.8 × 50
⇒ 40
This is the value of tangential acceleration.
Radial acceleration is given by
Where V = velocity of the disk = r
⇒ V = 0.8 × 10
⇒ V = 8
Radial acceleration
This is the value of radial acceleration.
