A block with mass M is placed on an inclined plane with slope angle q and is connected to a second hanging block with mass m by a cord passing over a small, frictionless pully. The coefficient of static friction μs and the coefficient of kinetic friction is μk. For what range values of of m will the blocks remain at rest if they are released from rest.
1 answer:
Answer:
The mass of the block m is:
Explanation:
Let's analyze the block by parts
For the block M
(1)
Where:
T is the tension W(x) is the component of the weight in the x-direction F(f) is the friction force
For the block m
(2)
Now, let's combines equation (1) and (2):
Finally, let's solve it for block m.
I hope it helps you!

P = m*v conservation of momentum suggests initial momentum equals final momentum mv-initial = mv-final (0.0010 kg)(50 m/s) = (0.0010 kg + 0.35 kg)v thus: v = (0.0010)(50)/(0.351) = 0.142 m/s
Answer:4.8 m/s^2
Explanation:
mass=10.5kg
Force=50.5N
Acceleration =force ➗ mass
Acceleration =50.5 ➗ 10.5
Acceleration =4.8 m/s^2
Acceleration = change in velocity/change in time so... a = 20 m/s / 2 secondsa = 10 hope that helps :)
Answer: A method of classifying stars by their temperatures and compositions.
Explanation:
our speed is given as
towards friend
Speed of the friend
away from us
now relative velocity with respect to our friend is given as
so here the relative velocity will be 3 m/s towards the friend
so friend will see that we are moving towards him with relative velocity of 3 m/s
