A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 43.0 m/s; when it leaves the bat, the ball is traveling to the left at an angle of 31.0 degree above horizontal with a speed of 51.0 m/s. The ball and bat are in contact for 1.71 ms.

Find the horizontal component of the average force on the ball. Take the x-direction to be positive to the right.

N

Explanation:

We are given that

Mass of baseball=m=0.145 kg

Initial velocity of ball=u=43 m/s

Speed, v=

Time, t=1.71 ms=

Horizontal component of the average force on the ball=

Horizontal component of the average force on the ball

Horizontal component of the average force on the ball=N

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
