Answer:
average velocity is 7m/s
avg acceleration is 4m/s
Explanation:
s=6-3t+2t2
putting 1 in t
s=6-3×1+2×1
s1=5
now putting t=4
similary by solving
s2=26
now
avg velocity= s2-s1/t2-t1
=26-5/4-1
=21/3
=7m/s
now for acceleration differentiat the equation
ds/dt=d/dt×6-d/dt×3t+d/dt×2t2
v= -3+4t
putting 1 In t
v1=1
similarly putting 4 in t
V2=13
now
avg acceleration is V2-v1/t2-t1
solving
avg acceleration is 4m/S2
