If the velocity of a pitched ball has a magnitude of 47.0 m/s and the batted ball's velocity is 50.5 m/s in the opposite directi
Naya [18.7K]

Answer:

The magnitude of change in momentum of the ball is 97.5 m and impulse is also 97.5 m

Explanation:

Given:

Velocity of a pitched ball v _{i} = 47 \frac{m}{s}

Velocity of ball after impact v_{f}  = -50.5 \frac{m}{s}

From the formula of change in momentum,

  \Delta P = m (v_{f} -v_{i}  )

Here mass is not given in question,

Mass of ball is m

Change in momentum is given by,

\Delta P = m (-50.5 -47)

\Delta P = -97.5 m

Magnitude of change in momentum is

\Delta P = 97.5 m

And impulse is given by

 J = \Delta P

J = -97.5 m

So impulse and

Therefore, the magnitude of change in momentum of the ball is 97.5 m and impulse is also -97.5 m

A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. after the collision, the first ball moves at 5.39
kodGreya [7K]
<span>To do this question, we need to know that momentum is conserved, meaning the overall velocity of the two balls has to be the same before and after the collision.  </span>

<span>After collision... </span>

<span>Ball 1: 4.33m/s *cos 30 = 3.75 m/s (x-component) </span>
<span>4.33m/s * sin 30 = 2.165 m/s ( y-component) </span>

<span>Ball 2 (struck ball): 5 m/s - 3.75m/s = 1.25 m/s (x-component)  </span>
<span>-2.165 m/s (y-component) note: it has to be in the opposite direction to conserve momentum </span>

<span>tan-1(2.165/1.25) = 60 degrees </span>
<span>Struck ball's velocity = sqrt(1.25^2 + 2.165^2) = 2.5 m/s at 60 degree with respect to the original line of motion.  </span>

<span>Hope you understand!</span>

A metal sphere has a charge of +10C. What is the net charge after 8.0 x 10^13 electrons have been placed on it?
masya89 [10]

Answer: 9.9999872 C

Explanation: In to answer this question we have to use the charge of the electron, that is eqaul to -1.6*10^-19 C.

After that, we have to calculate the charge given by 8.0*10^13 electrons, then we an additional charge of: 8.0*10^13 * -1,6*10^-19 C=1.28*10^-5C

Finally the net charge of the metal sphere, initially charged by +10C is:

10C-1.28*10^-5C=9.9999872 C
