Answer:
A=3.33m/s
B=3.11m/s
Explanation:
Speed = total distance/time taken to cover distance
hence,
S=d/t
s=32.0/9.60
s=3.33m/s
acceleration due to gravity
v=u+at
that is (v=final velocity,u=initial velocity,a=acceleration and t= time)
from the formula
2.10=32.0+a*9.60
2.10=32.0+9.60a
CLT
9.60a=32.0-2.10
9.60a=29.9
a=29.9/9.60
a=3.11m/s
hope it correct!?
