Answer 1

Answer:

⁸

Explanation:

Answer 2

Answer:

The mass of the car is 1225 kg.

Explanation:

Given Data :

The Momentum of the car (p) = 24,500 kgm/sec

The car's velocity (v) is 20 m/s.

To Find :

The mass of the car.

Formula To Be Used :

The momentum(p) of any body is given by

p = mv

where v is the velocity and m is the mass.

Solution:

The formula for momentum (p) is as follows,

p = mv

Since we need to calculate the mass of the car, then

$m = \frac{p}{v}$

Substituting the values in the above formula to calculate the mass of the car, we have

24500 kgm/s = m × 20 m/s

So,  $m = \frac{p}{v} = \frac{24500}{20} = 1,225$

Therefore, the mass of the car is 1225 kg.
