in a softball game, a batter hits the ball at the velocity of 27m/s and angle of 40 shown below. What is the maximum range of th

Nata [24]

Answer:

R = 73.25 m

Explanation:

We have,

Initial speed of the ball is 27 m/s

It is projected at an angle of 40 degrees

The maximum range of the ball is given by :

$R=\dfrac{u^2\sin2\theta}{g}$

Plugging all the values we get :

$R=\dfrac{(27)^2\sin2(40)}{9.8}\\R=73.25\ m$

So, the maximum range of the ball is 73.25 m

1 Hz

Explanation:

Frequency shift is given as

={ ( Vsound +V/ V sound -V) -1}f emitted

So by substitution we have

= { 1540+4E-4/1540-4E)-1) 2*10^6

= 1Hz

The acceleration of a falling rock that was initially moving 5 m/s, and had a final velocity of 11 m/s after accelerating for 3

yanalaym [24]

Answer:

2 m/s²

Explanation:

Given:

v₀ = 5 m/s

v = 11 m/s

t = 3 s

Find: a

v = at + v₀

11 m/s = a (3 s) + 5 m/s

a = 2 m/s²
