Answer:
A picture of a baseball being thrown tworad a batter at home plate.
Answer:
Explanation:
The horizontal component of the velocity = 19.5 cos 36.5 = 15.67m /s
The vertical component = 19.5 sin36.5 = 11.6 m /s
height h = 15.5
we shall first find the time of fall of the ball into water
vertical displacement = height = 15.5 ( positive and g will be positive as it is downwards .
s = ut + 1/2 gt²
15.5 = - 19.5 sin36.5 t + 1/2 x 9.8 x t²
4.9 t² - 11.6 t - 15.5 = 0
t = 3.31 s
During this period ball will travel in horizontal velocity of 15.67 m /s uniformly
horizontal displacement before touching water
= 3.3 x 15.67
= 51.7 m .
The formula for density is ρ=m/v where ρ is density, m is mass and v is volume.
The momentum of the water balloon at the given speed is 7.2 kgm/s.
The given parameters:
- <em>Speed of the water balloon, v = 18 m/s</em>
- <em>Mass of the balloon, m = 0.4 kg</em>
The momentum of the water balloon is calculated as follows;
P = mv
<em>Substitute the given values of </em><em>mass </em><em>and </em><em>velocity </em><em>as follows;</em>
P = 0.4 x 18
P = 7.2 kg m/s.
Thus, the momentum of the water balloon at the given speed is 7.2 kgm/s.
