Answer:
The recoil velocity of the projectile is 0.0025m/s
Explanation:
Given:
Mass of the projectile =0.005kg
Mass of the launcher = 1500kg
Velocity = 750 m/s.
To Find:
The recoil velocity of the projectile = ?
Solution:
The recoil velocity is the obtained by dividing the "recoil momentum" by the "mass of the recoil body". The recoil momentum is equal to the momentum of the other body. The momentum of the other body is equal to it mass times its velocity.
Lets find the recoil momentum,
Recoil momentum = mass of the projectile X velocity
Recoil momentum =
Recoil momentum = 3.75
Now Recoil Velocity,
Recoil Velocity =
Recoil Velocity =
Recoil Velocity = 0.0025m/s
Before going to answer this question, first we have to understand centripetal force.
The centripetal force is the force which is required to keep the body along its circular path.The direction of the force is along the radius and towards the centre.
Here m is the mass of the body,v is the velocity of the body and r is the radius of the circular path.
When a body moves in a circular path,its velocity at any point is the tangent drawn at that point.
As centripetal force acts along the radius, it must be perpendicular to the velocity of the body.
Hence the correct answer to the question is- It acts perpendicular to the velocity and is directed toward the center of the circle.
