General Chit-Chat everyday

1.) Calculate the acceleration of a car (in hm/h-s) that can go from rest from 100 km/h in 10 s.

2.)Calculate the instantaneous speed (in hm/h-s) that can go from rest to 100 km/h to 10 s.

3.)Calculate the speed (in m/s) of a skateboarder who accelerates from rest for 3 seconds down a ramp at an acceleration of 5 m/s2.

4.)Calculate the instantaneous speed of an apple that falls freely from a rest position and accelerates at 10m/s2 for 1.5 seconds.

5.)What is the acceleration of a bus that goes from rest to speed of 50 km/h in 10 s? (Hint: You can express acceleration in units of km/h)

6.)On a distant planet a freely falling object gains speed at a steady rate of 20 m/s during each second of fall. Fine its acceleration.

9.)What is the acceleration of a ball that starts from rest and rolls down a ramp, gaining a speed of 25 m/s in 5 s?

10.)Kenny Klutz drops his physics book off his aunt's high-rise balcony. It hits the ground below 1.3 s later. With what speed does it hit?

Sluggy? xD

Thanks and Rep+ will be given. Also 20k vbux.

LOL..
hey dont look at me i cant help you O.o

[ItsmYarD]

well these are really easy well i hope i can do them
here r my answers
and this belong to homework help not request section

2. nv learned this

3. 15ms^-1

4. nv learned this

5. 5kms^-2

6. 20ms^-2 (wow this one is the easiest)

9. 5ms^-2

10. 10ms^-1 not sure bout this one

well here u go xD
