Question

Jesse travels 3.0 meters east and then turns and travels 4.0 meters north. The trip requires 35 seconds. What is his velocity?

A) 0.14 m/s
B) 0.14 m/s, northeast
C) 5.0 m/s, northeast
D) 5.0 m/s, southwest

Answer 1

B.) 0.14 m/a, northeast is your answer.

Answer 2

0.14 m/s, northeast

Step-by-step explanation:

It is given that,

Distance travelled in east direction,
`x_1=3\ m`

Distance travelled in north direction,
`x_2=4\ m`

The shortest path or the displacement of Jesse is,
`x=√(x_1^2+x_2^2)`

`x=√(3_1^2+4_2^2)`

x = 5 m ( in northeast direction )

Time taken, t = 35 seconds

Jesse's velocity is defined as the net displacement divided by total time taken i.e.

`v=(x)/(t)`

`v=(5\ m)/(35\ s)`

v = 0.14 m/s

So, the velocity of Jesse is 0.14 m/s and it is in northeast direction. So, the correct option is (b) "0.14 m/s, northeast".
