Answer:
Impulse will be 12 kgm/sec
So option (b) will be correct option
Explanation:
We have given mass of the baseball m = 0.15 kg
Ball speed before hit
Ball speed after hitting ( negative direction due to opposite direction )
We have to find the impulse
We know that impulse is equal; to the change in momentum
So change in momentum =
So option (b) will be correct option
V=2.35×108m/s. That's the answer
Answer:
The additional force is
Explanation:
From the question we are told that
The horizontal force in one direction is
The horizontal force in the opposite direction is
The negative sign shows that it is acting in the opposite direction
Generally for the box to remain stationary the net force on it must be equal to zero that is
Where is the additional force required
So
substituting values
Answer:
I'm pretty sure it is Edwin Powell Hubble and Albert Einstein
