If a car is moving on a road at 70 km/hr going due north, and then changes direction and starts traveling north-east staying at 70 km/hr, what happens to its speed and velocity? answers are in the link guys

Velocity of the car changes while the speed will remain the same

Explanation:

As we know that the speed is the magnitude of rate of change in the position of the object

So here we have

while for finding velocity we know that it is rate of change in the position along with the direction of the motion

So it is given as

so here we can say that magnitude of the velocity in both is same while the direction is different

so correct answer will be

Velocity of the car changes while the speed will remain the same
