solve this question?????​

Answer 1

Answer:

Given :-

Initial velocity (u) = 0 m/s

Distance (s) = 400 m

Time (T) = 10 sec

Mass = 5000 kg

To Find :-

Acceleration and force

Solution :-

By using second Equation of motion

$\sf \: s \: = ut + \dfrac{1}{2} {at}^{2}$

Here,

S = Distance

U = Initial velocity

T = Time

A = Acceleration

$\sf \: 400 = 0 \times 10 + \dfrac{1}{2} \times a \times 10 {}^{2}$

$\sf \: 400 = 0 + \dfrac{1}{2} \times a \times 100$

$\sf \: 400 = 0 + 1\times 50 \: a$

$\sf \: 400 = 50a$

$\sf \: a = \cancel \dfrac{400}{50}$

$\sf \: acceleration \: = 8 \: mps {}^{2}$

Now,

Let's find force exerted

$\sf \: force \: = mass \times acceleration$

$\sf \: force = 500 \times 8$
