When a baseball player catches a baseball, the glove "gives" or moves backward. How does this movement affect the change in mome

ntum of the baseball?

Answer:

The change in momentum increases because the impact time increases.

Explanation:

When a baseball player catches a baseball, the glove "gives" or moves backward. Momentum of a body is equal to the product of mass and velocity. Also, the change of momentum of an object when it is acted by a force is called impulse. It is represented by J. Mathematically, it can be written as :

J=F.\Delta t=m\Delta v

F is applied force

\Delta t is the time taken by an object to change its momentum

The momentum depends on the force and the time of impact. In this case, as the a baseball player catches a baseball, the gloves move in backward direction. By doing so, the ball comes to rest in larger time.

So, the change in momentum increases because the impact time increases.

vagabundo [1.1K]
It's not so much a "contradiction" as an approximation. Newton's law of gravitation is an inverse square law whose range is large. It keeps people on the ground, and it keeps satellites in orbit and that's some thousands of km. The force on someone on the ground - their weight - is probably a lot larger than the centripetal force keeping a satellite in orbit (though I've not actually done a calculation to totally verify this). The distance a falling body - a coin, say - travels is very small, and over such a small distance gravity is assumed/approximated to be constant.

Mazyrski [523]

Answer: Magnitude of electric field = 6.77×10^11N/C

Explanation: Electric field= E =KQ/ r ^2

Given:

Total charge Q=53.2nc

Radius 84cm= 0.84m

Coulombs constant K= 8.987x10^9NmC^-1

E =(( 8.987×10^9) × 53.2) /(0.84^2)

E = ( 4 . 777 ×10 ^ 9 )/ 0.7056

E = 6.77 × 10^ 11 NC^-1
