Hi everyone in this question we have to calculate the acceleration of the cart without falling the block.
00:06
Okay, this is the gart, this is block.
00:09
Here we can say this force, this is acceleration and its static frictional force, new a static friction coefficient.
00:24
So this is gravity.
00:28
This is gravity.
00:29
So we draw the free body diet.
00:31
For this so this is the block or got this is the frictional force static friction and this direction acting acceleration and here is gravitational force so we have weight force if equal to m g then for this x component here acting the the force for x component.
01:12
X component can write the force summation of f x vector acceleration force f f, a.
01:29
So, f which is equal to m, a, for x common, m, a, x.
01:36
For y component, we can say, we are acting that friction, static friction, here the weight forces.
01:45
So we can write this y component which is equal to summation of f y static friction.
02:01
It's opposite, both are equal and opposite.
02:05
So s f minus f weight is equal to m, a, y component.
02:14
This is so m, a, y.
02:17
Here, f, s, f, static friction, which is equal to m, a, component.
02:22
Which is equal to a force of weight or gravitational force...
