Acar travels at a velocity of 10 m/s north for 50 s. which of the following
equations correctly determines the car's displacement?
a) displacement = 50 s/(10 m/s)
b) displacement = (10 m/s north) /50 s
c) displacement = (10 m/s north) * 50 s
d) displacement = 50 s/(10 m/s north)

Explanation:

Given that,

Velocity of car, v = 10 m/s (towards north)

Time, t = 50 s

The shortest path covered by the car is called its displacement. Mathematically it is given by

d = v × t

v is the velocity of the car

t is the time taken

Here, displacement = (10 m/s north) × 50 seconds

So, the correct option is (c).
