A Car Starts From Rest And Rolls Down A Hill With Constant Acceleration. It Travels A Distance Of 500 M In 20 Sec. Calculate Its Acceleration.

Jawaban: #1:

A car starts from rest and rolls down a hill with a constant acceleration. It covers a distance of 500 m in 20 seconds. So the acceleration is 1,25 m/s²

Discussion

Is known :

distance (s) = 500 m

time (t) = 20 second

Asked :

acceleration (a)?

Answered :

Find the speed first

v = s/t

v = 500/20

v = 25 m/s

Find acceleration

a = v/t

a = 25/20

a = 1,25 m/s²

Conclusion

So, the acceleration is 1,25 m/s²
