Question

A body of mass 5kg is moving with a velocity of 10 m a force is applied to it so that on 25 sec it attains a velocity of 35m sec calculate the value of the force applied

Answer 1

Answer:

Ans:F=5×1=5N

Explanation:

F=ma

given, m=5kg a=(u=10m/s v=35m/s t=25sec) =( v-u)/t=(35-10)/25 = 1

F=ma

Answer 2

❍ CONCEPT

This question is related to force and pressure. First of all let's know about force.

what is force ?

force is a pull or push which changes the state of rest of motion of an object.

SI unit of force is Newton (N)

According to the question

• mass - 5 kg
• initial velocity - 10 m/s
• final velocity - 35 m/s
• time taken - 25 sec

Formula of force- Mass × acceleration

to solve this question we need to find acceleration.

Formula of acceleration

$\large \frac{\sf \: final \: velocity \: - initial \: velocity}{\sf \: time}$

by using formula, we get

$\leadsto \large \frac{35 - 10}{25}$

$\leadsto \large\frac{25}{25} = \sf\green{1m/s²}$

Acceleration is 1m/s²

Formula of force

mass × Acceleration

by using formula we get

$5 \times 1$

$\sf\purple{ = 5N}$

Force applied on body is 5N
