Question

If there is a block of mass 2kg and a force of 5N is acting in it in the positive x- direction,and a force of 3N in the negative x-direction, then what would be its acceleration?​

Answer 1

Answer:

Explanation:

Assume initial velocity of 1.5 m/s is in the x-direction

Since there are no forces on it in this direction, there will be no acceleration.

So, distance S  

x

​  

=1.5×4=6m

In the y-direction, F=5N and m=5kg

Acceleration in y=direction,
