Answer:
8.44 m/s.
Explanation:
Change in Potential Energy = Mass x Acceleration From Gravity x H2 - H1
Kinetic Energy = 1/2 (mass) x [(v2)^2 - v1^2]
g * h = 1/2 * v^2
(9.8) x (2.27) = 1/2 * (v)^2
v^2 = 2[(9.8) x (2.27)]
v = 6.67 m/s
g * delta h = 1/2 * delta v^2
(9.8) x (2.27 - 0.903) = 1/2 * [(v2)^2 - (6.67)^2]
v2^2 = 71.2821
v2 = 8.44 m/s
Answer:
Explanation:
We are given that
Initial velocity of baseball=u=-41m/s
Because final and initial velocity are in opposite direction
Final velocity of baseball=v=47m/s
Time=t=1.9 ms=
1 ms=
We have to find the acceleration .
We know that
Acceleration=
Using the formula
Acceleration=
Acceleration=
Answer: this answer is D. That's what I think it is
Explanation:
We know that tangential acceleration is related with radius and angular acceleration according the following equation:
at = r * aa
where at is tangential acceleration (in m/s2), r is radius (in m) aa is angular acceleration (in rad/s2)
So the radius is r = d/2 = 1.2/2 = 0.6 m
Then at = 0.6 * 5 = 3 m/s2
Tangential acceleration of a point on the flywheel rim is 3 m/s2
