no 6 7 8

Answer 1

6. a. Vt=v0+at
18=0+1,5t
t=18/1,5
t=12s
b. s=v0.t+1/2at^2
S=0+1/2.1/5.144
s=108m

7. 90km/h=25m/s
a.vt=v0+at
0=25+20a
-25=20a
a=25/20
a=1,25m/s^2

b.s=vo.t+1/2at^2
s=25.20+1/2.-1,25.400
s=500-250
s=250m

8. a s=vo.t+1/2at^2
330=v0t+1/2.2,4.t^2
330-1,2t^2=v0t
330-1,2.225=v0.15
60=v0.15
v0=4m/s

b.Vt=v0 +at
vt=4+2,4.15
Vt=4+36
Vt==40m/s
