Question

A bus travels 1425 m in 75.
(a) What is its speed?
(a) What other piece of information do we need in order to state its velocity?

Answer 1

Answer:

19m/s

Explanation:

a) speed = distance/time

If considering 75 sec

Speed = 1425/75

= 19m/s

b)Assuming the object is moving by uniform motion (i.e., at constant velocity), the two pieces of information we need to know are:

1) the distance covered by the object, S

2) the time it takes for the object to travel that distance, t

In fact, the velocity of the object is defined as the ratio between these two quantities:

v= S ( displacement)/ t (time)
