Question

Calculate the momentum of a toy car of mass 20 gram moving with a speed of 5 m per second

Answer 1

Heya......!!!

_____________________________

Given In The Question :-

•--» Mass of Toy Car = 20 gm = 20 / 1000 Kg .

•--» Speed of Toy car = 5 m/s

We know that a Body of mass ( m ) with velocity ( v ) then it's Momentum ( P ) is given by :-»

=> P = mv

putting values in the formulae :-»

=> P = 20 / 1000 × 5
=> P = 1 / 10

♦ Momentum of toy car => 0.1 Kg m/s

Hope It Helps You ☺

Answer 2

Hey frnd..

Momentum is denoted as "p"

Momentum is the product of mass and velocity..

Now 200 g has to converted to kg..

so.. 200 ÷ 1000 = 0. 2 kg

p = m × v

p = 0. 2 × 5

=1. 0 kgm/s

Hope it helps u frnd..
