George and harriot walk with an average velocity of .95 m/s eastward. if it takes them 30
minutes home, what is their displacement in kilometers?

1.71 km

Explanation:

Convert 30 minutes to seconds:

30 min × (60 s / min) = 1800 s

Find the displacement:

0.95 m/s × 1800 s = 1710 m

Convert to kilometers:

1710 m × (1 km / 1000 m) = 1.71 km

1.71km

Explanation

Velocity is defined as the change in displacement of a body with respect to time. Displacement specifies direction and as such is a vector quantity.

Mathematically;

Velocity = displacement/time

Displacement = velocity ×time

Given velocity of the body = 0.95m/s

Time = 30minutes

Time = (30×60)seconds

= 1800seconds

Displacement = 0.95×1800

Displacement = 1710m

Since 1000m = 1km

1710m to km will give;

1710/1000

= 1.71km

he kicked it 10 feet straight up into the air? i think this works.

i think they are all correct

explanation:

they seem good
