Question

Two forces F1 and F2 are acting on a body of mass 5 kg as shown in the figure. If F1 = 20 N and F2 = 5 N, then what will be the acceleration of the body ?
i will mark the brainliest whoe ever answers it first

Answer 1

There is no figure in the question. So I am taking both forces acting in opposite direction.

F1 = 20 N and F2 = 5 N
m = 5Kg

Net force = F1 - F2 = 15N

F= ma
a = F/m = 15/5 = 3

Answer 2

Answer:

The acceleration of the body will be 3 m/s².

Explanation:

Given that:

F1 = 20 N and F2 = 5 N

Mass m = 5Kg

So the Net force = F1 - F2

= 15N

Now Force F = m × a

a = F/m

a = $\frac{15}{5}$

Acceleration a = 3 m/s².

What is the acceleration of a body moving?

• Since acceleration is defined as the "rate of change of velocity" per unit of time, a body moving at a constant speed will experience zero acceleration. Therefore, the rate of "change of velocity" (dv = 0) will be zero if the body has uniform velocity.
• A moving object's acceleration is negative when it comes to a stop since its velocity is zero. thus, there is no acceleration.
• The body will not accelerate in the case of uniform rectilinear motion. In this case, the object's actual speed and average speed will be the same.
• Zero acceleration indicates that there is no net force acting on the object.

Thus, the rate at which velocity changes over time, both in terms of speed and direction, is defined as the acceleration.
