Question

What is the acceleration of a cabinet of mass 45 kilograms if Jake and Ted push it by applying horizontal force of 25 newtons and 18 newtons respectively in the same direction

Answer 1

Answer:

$a=0.96\ m/s^2$

Explanation:

Given that,

Mass of cabinet, m = 45 kg

Two horizontal force of 25 newtons and 18 newtons respectively in the same direction.

When the forces are acting in same direction, the net force is equal to the sum of forces i.e.

F = 25 N + 18 N = 43 N

Let a is the aceleration of the cabinet

So,

F = ma

$a=\dfrac{F}{m}\\\\a=\dfrac{43}{45}\\\\a=0.96\ m/s^2$

So, the acceleration of the cabinet is $0.96\ m/s^2$.
