In the previous parts, you obtained the following equations using Newton's 2nd law and the constraint on the motion of the two blocks: m2a2x=T−m2gsin(θ),(1) m1a1y=T−m1g,(2) and a2x=−a1y.(3) Solve these equations to find a1y. Before you enter your answer, make sure it satisfies the special cases you already identified: a1y=−g if m2=0 and a1y=0 if m1=m2 and θ=π/2. Also make sure that your answer has dimensions of acceleration. Express a1y in terms of some or all of the variables m1, m2, θ, and g.

Explanation:

1)

The system of equations that we have in this problem is:

(1)

(2)

(3)

Here we want to solve the system for .

First of all, we isolate T from eq.(2):

And we substitute this expression into eq(1):

Solving for , we get

Now we can substitute this into eq(3):

And re-arranging for we find:

2)

We see that this solution satisfies all special cases. In fact:

- If ,

- If and , we get

Also, this solution has dimensions of acceleration. In fact:

- The term at the numerator is in the form , where mass is in kilograms and g is in meters per second squared (so, it is in the form mass*acceleration)

- The term at the denominator is a mass, so it is in kilograms

This means that is (mass*acceleration)/(mass), therefore it has dimensions of acceleration.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
