Question

A toy car of mass 250g is moving with a velocity of 5m/s.What is its momentum?

Answer 1

Here's your answer..

_______________________

Mass of the toy car is 250g.
=>0.25kg
Velocity of car is 5m/s.

So,
Momentum= Mass ×Velocity
$= > 0.25 \times 4 \\ = > 1000$
Hence,
Momentum of car is 1.25 kg.m/s

Answer 2

Mass=250gram
Change in kg =0.250kg
Velocity = 5m/s
Momentum = mass × Velocity
= 0.25×5
=1.25
