Question

1. A kangaroo hops 84 m to the east in 7 seconds.

o What is the kangaroo's speed? 12 m/s
o What is the kangaroo's velocity?

Answer 1

Step-by-step explanation:

Given parameters:

Distance hopped = 84m

Displacement = 84m due east

Time = 7s

Unknown:

Speed of kangaroo = ?

Velocity of kangaroo = ?

Solution:

To solve this problem,

Speed =
`(distance)/(time )` =
`(84)/(7)` = 12m/s

Velocity =
`(displacement)/(time)` =
`(84)/(7)` = 12m/s due east
