Question

A force of 10 N acting on a 10 kg mass for 4 sec provides it some velocity. Calculate the velocity​

Answer 1

Answer:

answer in attachment.

Answer 2

Given :

• Force (F) = 10 N
• Mass (m) = 10 kg
• Time (t) = 4 seconds

To find :

• The Velocity

According to the question,

➤ At first we have to use the formula of Force,

${\boxed{ \sf{Force = Mass \times Acceleration}}}$

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

$\implies \sf{ \cancel\frac{10}{10} {}^{ \: \: 1} = a}$

$\implies \sf{a = 1 \: {ms}^{2} } \green \bigstar$

So,the acceleration is 1 m/s²...

Now we will find velocity,

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

$\implies \sf{v = 0 + 1 \times 4}$

$\implies \sf{v = 4 \: m {s}^{ - 1} } \green \bigstar$

So,the velocity is 4 m/s...

_______....

• v stands for Final velocity
• u stands for Initial velocity
• a stands for Acceleration
• t stands for Time
