Question

wo cars are traveling from the same point. Car A has a velocity of 12.5 m/s while car B has zero velocity but an acceleration of 3.5 m/s 2 . How far apart will the cars be after 12.0 seconds?

Answer 1

The two cars will be 402 m apart after 12 seconds.

What is Velocity ?

Velocity is the distance travel in a specific direction per time taken. It is measured in m/s

Given that two cars are traveling from the same point. Car A has a velocity of 12.5 m/s while car B has zero velocity but an acceleration of 3.5 m/s 2 .

For car A after 12s:

Speed v = distance s / time t

v = s/t

12.5 = s/12

s = 12.5 × 12

s = 150 m

For car B after 12s:

• u = 0

• a = 3.5 m/s²

• s = ?

• t = 12s

s = ut + 1/2at²

s = 0 + 1/2 × 3.5 × 12²

s = 1.75 × 144

s = 252 m

If the two cars were on different direction, the distance between them will be 252 + 150 = 402 m

Therefore, the two cars will be 402 m apart after 12 seconds.
