Question

Katie and Liam play tennis every Saturday morning. When Katie serves the ball to Liam, it travels 9.5 meters, south in 2.1 seconds. What is the average velocity of the ball?

Answer 1

Answer:

The velocity of an object is found by the equation,

→

v

=

→

d

t

→

d

is the displacement

t

is the time taken

And so, we get,

→

v

=

9.5

m

2.1

s

≈

4.52

m/s

Since the original direction was south, then the ball will fly at a velocity of

4.52

m/s

heading towards the south direction.
