Question

A 25 kg cart has 125kg*/s of momentum. How fast is the car going

Answer 1

Answer:

25 m/s

Explanation:

Mass = 25 kg

Momentum = 125 kg m/s

Momentum = Mass x Velocity

Velocity = Momentum/Mass = 125/5 = 25 m/s

The velocity of the car is 25 m/s.

Hope this helps :)

Answer 2

Answer:-

Given:-

Momentum (P) = 125 kgm/s

Mass of the car (m) = 25 kg

We know that,

P = mv

(v is the Velocity of the object).

Hence,

→ 125 = (25) * (v)

→ 125/25 = v

→ 5 m/s = v

Therefore, the car is moving with a velocity of 5 m/s.

Additional Information:-

• Momentum is simply defined as the product of mass and velocity of an object.

• It is denoted by the letter P.

• P = mv

• S.I unit of momentum is kgm/s and C.G.S unit is gcm/s.

• 1 kgm/s = 10⁵ gcm/s.

• It is a vector quantity.
