It stats that an object is said to be at rest unless we would not apply any force .

Unknown Clashers 5 years, 1 month ago

First law of motion tells us that any body will not change its direction or state of motion until external force is applied. This law is also known as law of inertia

when there is no force then there will be no acceleration and when there is no acceleration there will be no force . by newtons second law we can prove it as f=ma if a =0 then f=0 and vice versa

ANSWER

A train is moving with a velocity of 30km/h due east and a car is moving with a velocity of 40km/h due north. What is the velocity of car as appearing to a passenger in the train.

Posted by Dweep Choudhary 4 years, 10 months ago

1 answers

Sia ? 4 years, 10 months ago

The velocity of car is given as -30i + 40j km/h.
The next step is |v| = √(30^2 + 40^2) = 50 km/h.
Hence, it will actually appear going North West at a speed of 50km/h.
