m/s? The velocity of a car after 20 seconds is …
O a. 120 m/s
O b. 150 m/s
O C. 80 m/s
O d. 100 m/s

A car is moving with an initial velocity of 20 m/s and then moving with constant acceleration of 4

Jawaban:

given : v1 = 20 m/s

a = 4 m/s^2

t = 20 s

ask :v2 …. ?

answer :

  • a = (v2 – v1)/ t
  • v2 = at + v1
  • = 4×20 + 20
  • = 100 m/s

Good luck….

Jawaban:

d. 100m/s

Penjelasan:

know

Vo=20m/s

a=4m/s²

t=20s

asked

vt=?

solution

The velocity of a car after 20 seconds:

vt=Vo+at

vt=20+4(20)

vt=20+80

vt=100m/s
