Question

A car has momentum, p=10880 kg m/s, east. If the car is traveling east at 16 m/s, its mass must be [m] kg.

Answer 1

Given :

Momentum of car = 10880 kg m/s

Velocity of car = 16 m/s

To Find :

We. have to find mass of the car$.$

Solution :

★ Momentum of body is measured as the product of mass and its velocity.

It is a vector quantity having both magnitude as well as direction.

SI unit : kg m/s or N s

Formula : p = m × v

• p denotes momentum
• m denotes mass
• v denotes velocity

★ Calculation :

⭆ p = m × v

⭆ 10880 = m × 16

⭆ m = 10880/16

⭆ m = 680 kg

∴ Mass of the car = 680 kg

Hope It Helps!

Answer 2

Answer:

The answer is 67.5 kg

Explanation:

To find the mass of an object given it's momentum and velocity we use the formula

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

where

p is the momentum

v is the velocity

From the question

p = 1080 kgm/s

v = 16 m/s

We have

$m = \frac{1080}{16} = \frac{135}{2}$

We have the final answer as

67.5 kg
