Question

what is the linear momentum of a toy car of mass 300 gm moving with a speed of 18 km/h ?

Answer 1

GiveN :

• Mass of toy car (m) = 300 g
• Speed of toy car (v) = 18 km/h

To FinD :

• Linear Momentum of car

SolutioN :

Convert mass to kilogram ,

→Mass = 300 g

→Mass = 300/1000 kg

→Mass = 0.3 kg

______________________

Convert Speed to m/s

→Speed = 18 km/h

→Speed = 18 * 5/18

→Speed = 90/18

→Speed = 5 m/s

______________________

Use formula for MomentuM :

→P = mv

→P = 0.3 * 5

→P = 1.5

$\therefore$ Linear momentum is 1.5 kgm/s.
