Answer 2

Answer:

Given:

Mass of the car = 1500kg

Initial velocity = 5m/s

Time 5 sec

To Find:

Force applied by the car.

Formula:

$\huge\bold\red{\mathfrak{F = m×a}}$

where ,

F is the force applied

m is the mass of the object

and a is the acceleration

Solution:

To find acceleration, we'll use second law of motion

that is ,

$\bold\red{\mathbb{s=ut+\frac{1}{2}a{t}^{2}}}$

$\bold{\mathbb{》100=5×5+\frac{1}{2}×a×25}}$

$\bold{\mathbb{》100=25+\frac{1}{2}×25a}}$

$\bold{\mathbb{》100=25+\frac{25a}{2}}}$

$\bold{\mathbb{》100-25=\frac{25a}{2}}}$

$\bold{\mathbb{》75=\frac{25a}{2}}}$

$\bold{\mathbb{》75×2=25a\implies 25a =75×2}}$

$\bold{\mathbb{》25a=150}}$

$\bold{\mathbb{》a = 150/25}}$

$\bold{\mathfrak{》a=6m{s}^{2}}}$

Now,

inserting the values in

》 F = m × a

》F = 1500 × 6

》F = 9000 N

hence ,the force applied be

$\boxed{\boxed{\boxed{\mathcal{F=9000N}}}}$
