Power of the glasses required is given as +2.5 D
this shows that person is having Farsightedness in which he can objects placed far clearly but he is not able to see clearly to the near objects
For normal vision near point of eye is 25 cm
Let say person can see the objects clearly at distance "d" from the eye
now from the formula

here given that


also we know that

from above equation now


So the distance of object must be 66.6 cm

Answer:
a) Her feet are in the air for 0.73+0.41 = 1.14 seconds
b) Her highest height above the board is 0.82 m
c) Her velocity when her feet hit the water is 7.16 m/s
Explanation:
t = Time taken
u = Initial velocity = 4 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²


b) Her highest height above the board is 0.82 m
Total height she would fall is 0.82+1.8 = 2.62 m

a) Her feet are in the air for 0.73+0.41 = 1.14 seconds

c) Her velocity when her feet hit the water is 7.16 m/s
