Question

A car is travel on a road with velocity of 20m/s in 10 sec mass of car is 200 kg. find force.​

Answer 1

Answer:

u=0

v=20m/s

t=10s

to find a....

a=v-u/t

a=20-0/10

a=2m/s²

to find force....

F=ma

=200×2

=400N

hope it helps.....

Answer 2

Given :

• Final Velocity (v) is 20 m/s
• Time (t) is 10 seconds
• Mass (m) is 200 kg
• Initial velocity (u) is 0 m/s

To find :

• Force (F)

At first we have to find acceleration then we will find force

By using Newton's first equation of motion

$\star \boxed{ \sf \purple{v = u + at}}$

According to the formula we will put the value

$\implies\sf{20 = 0 + a \times 10}$

$\sf \implies{20 = 10a}$

$\implies \sf{a = \frac{20}{10} = 2 \: {ms}^{2} \green\bigstar }$

So,the acceleration is 2 m/s^2...

Now,we will calculate the force

$\star \boxed{ \sf \purple{F = ma}}$

$\implies \sf{200 \times 2}$

$\sf \implies{400 \: N} \green \bigstar$

So,the force is 400 N
