i'm having trouble setting up the problem and choosing the formula to use please help on this. any help on any of these question is appreciated. 10 pts!
1.a bike accelerates from 0.0m/s to 4m/s on 4 s. What distance does it travel?
2. a student drops a ball from a window 3.5m above the sidewalk. the ball accelerates at 9.8m/s. how fast is moving when it hits sidewalk?
3. abike first accelerates from 0.0m/s to 5.0m/s in 4.5 s, then continues at this constant s[eed for another 4.5s. what is the total distance?
4. a car is traveling 20,s when driver sees a child standing on the road. he takes 0.8 s to react then steps on the brakes and slows to 7.0 m/s^2. How far does car go before it stops?
5. you throw a ball downward from a window at speed of 2.0 m/s the ball accelerates at 9.8m/s^2 How fast is it moving when it hits sidewalk 2.5 in below? how fast is it if you throw it up instead of down?
6. a truck is stopped at a spotlight . when the light turns green it accelerates at 2.5m/s at same instant a car passes the truck going 15 m/s/ when n where does truck catch up with the car?
7.a truck is traveling at 18m/s to the north. the driver, 500 m to the north and traveling south at 24 m/s puts on the brakes and slows at 3.5 m/s^2 where do they meet?
