Answer:
1. 18.25 m/s
2. 0 m/s
Explanation:
1.So the centripetal acceleration of the ball at this lowest point must be, taking gravity into account

The speed at this point would then be


2. Similarly, if T = mg, then the centripetal acceleration must be

As the ball has no centripetal acceleration, its speed must also be 0 as well.
It is Amperes(A), so the answer is A
<span>The momentum of the second ball will depend on the acceleration of the first moving ball.</span>
68% So 68/100 of freshwater is found in ice
If the speed of the particle is doubled. Then the value of the momentum also gets doubled.
<h3>What is momentum?</h3>
The sum of an entity's speed and mass is known as its linear momentum, translational momentum, or simply momentum in Newton's laws of motion. It has both a magnitude and a direction, making it a vector quantity. The SI unit of momentum is kg-m / s.
Let m be the mass and v be the velocity of an object. Then the momentum is given as,
P = mv kg-m / s
A particle is moving at a speed less than c / 2. If the speed of the particle is doubled.
P = m(2v)
P = 2mv
If the particle's speed is twice. The momentum's value is then increased by two.
