Answer:
U=3.19m/s
Step-by-step explanation:
using the newton's equation of motion as
s=ut+1/2at^2
S=distance
H=height the jumping flea attains
g=acceleration due to gravity
a=acceleration of the body
Therefore ,a body under free fall
a=-g
s=h
h=0.520m
g=9.80m/s^2
V^2= u^2-2*9.80*.52
V=o at maximum height
0=u^2-10.192
u=3.19m/s
Definition of terms
Velocity:
change in displacement per time
Acceleration: Is change in velocity per time
