Answer:
-5.1 kg m/s
Explanation:
Impulse is the change in momentum.
Change in momentum= final momentum - initial momentum=m +m
Plugging in the values= -0.15*24 - (0.15*10) (The motion towards the pitcher is negative as the initial motion is considered to be positive)
Impulse=-5.1 kg m/s (-ve means that it is the impulse towards the pitcher)
I'm pretty sure it's true. We glow with "Bioluminescence".
Answer:
705.6 m
Explanation:
time, t = 12 sends
initial velocity, u = 0
Acceleration due to gravity, g = - 9.8 m/s^2
As the object is falling freely so the initial velocity is zero.
Let the distance traveled by the body is h in time t = 12 s.
Use second equation of motion
Ad the distance is downwards so take it as negative
So,
h = 705.6 m
Thus, the distance traveled in 12 second is 705.6 m
Given:
The mass of each sphere is
The distance between the two spheres is r = 2 m
To find the gravitational force that one sphere exerts on the other.
Explanation:
The gravitational force is caculated by the formula
Here, the universal gravitational constant is
Substituting the values, the gravitational force will be
Final Answer: The gravitational force that one sphere exerts on the other is 1.04 x10^-8 N.
