Question

1. calculate speed of a car moving 10 miles and 15 minutes
2. calculate the distance a car travels if it has a speed of 50 km/hr and travels for 30 seconds.
3. what is the acceleration of a car with a beginning speed of 50 ft/s and comes to a stop. the car traveled for 10s.
5. an object dropped from a building. how long does it take to hit the ground if the speed at which it hits the ground is 49m/s? ignore friction.
6. what is your average speed of you run 50 m at a speed of 4.5m/s and then walk 200 m at 0.5 m/s?

Explanation / Answer

1) 17.88m/s

2)416.67m

3)50ft/s=15.24m/s

15.24=ax10

a=1.524m/s^2

4) 49^2=2gxh

h=122.375

h=1/2gt^2

t=4.995 sec

6) (50+200)/(50/5.5+200/0.5)=0.608m/s
