Answer 1

Odpowiedź:

v1=2m/s

v2=8m/s

v3=9m/s

t1=4s

t2=7s

t3=9s

t4=12s

s=v1*t1/2 +v1*(t4-t1)+(v2-v1)*(t2-t1)/2+(v2-v1)*(t4-t2)+(v3-v2)*(t4-t3)/2

s=2m/s*4s/2+2m/s*8s+6m/s*3s/2+6m/s*5s+1m/s*3s/2

s=4m+16m+9m+30m+1,5m

s=60,5m

a1=v1/t1

a1=2m/s/4s

a1=0,5m/s²

a2=(v2-v1)/t2-t1)

a2=6m/s/3s

a2=2m/s²

a3=0

a4=(v3-v2)/(t4-t3)

a4=1m/s/3s

a4=0,33m/s²
