A car travels along a straight road 100 m east then 50 m west. Find the speed and velocity of car

Answer»

ANSWER:

DISTANCE travelled is the total LENGTH of the PATH travelled by the car.

D=100M+50M=150M

Displacement is the linear separation between initial and final points. Here the car moved 100 m forward and then 50 m backward. Then,

S=100M-50M=50M
