Answer:
a)
b)
c)
Explanation:
From the question we are told that
Mass of soft rubber
Spring compression
Stiffness constant
Ball Distance
Frictional force
a)Generally the equation for motion of the second ball according to Newton's law is given by
b)Generally for speed to be at maximum spring force must equal frictional force
At distance
Therefore
Ball is at maximum speed at
c)Generally maximum velocity is represented mathematically as
Answer:
Centripetal forces are directed toward the center of a circle.
Hope this helps.
Explanation:
Answer: 655.7 nm
Explanation:
Given
The slits are separated by
Distance between slits and screen is
Adjacent bright fringes are apart
Also, the distance between bright fringes is given by
The impulse exerted by the ball on the bat is THE SAME
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 :
Plugging all the values we get :
So, the maximum range of the ball is 73.25 m
