Yes. Partly. Also on the size and shape of the object, and also on what material it's IN at the time ... like air, water, Helium, Jello, etc.
A projectile has some form of thrust to propel it in the desired direction, while an object in free fall has no extra force guiding/propelling it
A=(vf-v₀)/t
Data:
vf=100 m/s
v₀=70 m/s
t=1.5 s
a=(100 m/s - 70 m/s)/1.5 s=30 m/s / 1.5 s=20 m/s².
answer: C. 20 m/s²
