centripetal acceleration is given by formula
given that
now we have
so the ratationa frequency is given by
Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
Answer:
Option (b) is correct.
Explanation:
The motion under the influence of gravity is called projectile motion.
The acceleration due to gravity is constant through out the motion and it is always acting downwards.
When an athlete jumps and follow the projectile path, it always have the same horizontal velocity as there is no acceleration in the horizontal direction.
Also he has the vertical acceleration constant which is equal to the acceleration due to gravity and acts towards the center of earth.
Option (b) is correct.
Answer:
there yah go that's the answer
Answer:
For the dry and static friction materials, some of these are Rubber, Aluminum, Gold, Platinum,
Explanation:
High friction materials has higher coefficient of friction (COF).
