Question

A car covers 200 m in 24 s, 100 m in the next 12 s, and then 100 m in another 12s. The car is in __________ motion.
i) retarded motion
ii) accelerated motion
iii)uniform motion
iv) non uniform

Answer 1

Answer:

A car covers 200m in 24 s, 100min next 12 s, and then 100 m in another 12 s.

The car is in (iii) uniform motion.

Step by Step Explanation:

           Distance      Time taken     Equation

Let         200m               24s                  (1)

              100m                12s                  (2)

              100m                12s                  (3)

(1) + (2)

100 + 100, 12 + 12

200m, 24s - (4)

Since (1) = (4)

Therefore, the car is in uniform motion.

Hope you got your answer.
