Hey dear,
◆ Answer-
a = 3.6 m/s^2
◆ Explaination-
# Given-
a1 = 3 m/s^2
t1 = 2 s
a2 = 4 m/s^2
t2 = 3 s
# Solution-
Total time = 2 + 3 = 5 s
Let a be average acceleration.
Then we have the eqn,
at = a1t1 + a2t2
a × 5 = 3×2 + 4×3
5a = 6 + 12 = 18
a = 18/5
a = 3.6 m/s^2
Therefore, average acceleration of the is 3.6 m/s^2.
Hope this helps...
