Question

Please help me find a) and b):

Answer 1

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!?
