Question

1) If the velocity of a car is 45 km/h west, how far can it travel in 0.5 hours?

2) What is the velocity of a rocket that goes 700 km north in 25 seconds?

3) A driver starts his parked car and within 5 seconds reaches a speed of 60 km/h, as he travels east. What is his acceleration?

4). A slug traveling at 3 mm/h, East decided to race the slug next to him increasing his velocity to 5 mm/h, East
in one hour. What was the slug’s acceleration?

5) In a summer storm, the wind is blowing with a velocity of 8 m/s north. Suddenly in 3 seconds, the wind’s
velocity is 23 m/s north. What is the wind’s acceleration?

Answer 2

1 velocity = 45km/hr
Time = 0.5 hr or 30 min or 1/2 hr
Distance travel = 45 ×1/2 km
= 22.5 km
2 distance = 700 km or 700000m
Time = 25 sec
Velocity = 700000 / 25
= 28000 m/s
