a motor car is going due north at a speed of 50km per hour. it makes a
900 left turn without changing the speed. the change in the velocity of the car is about
Mechanics | Relativity
We need to find the change in the velocity of the car .
Solution:
We can consider these velocities on an xy - plane with the vectors
,
Initial Velocity = a motor car is going due north at a speed of 50km per hour.
Final velocity = it makes a 90 Degrees left turn without changing the speed
= It moves in the direction of west with the speed 50 km/h
Now,
Change in velocity (Δv) = Final velocity – Initial velocity =
direction (west) and direction (south), so the total change in velocity will be pointing towards the southwest.
Answer: Yes
Change in velocity =
