100 Pascal is equal to:
A) 100 Newton B) 1000N/m2 C) 100N/m2 D) 10,000N/m2 E) None of these

Choice C)  100 N/m^2

Work Shown:

1 pascal = 1 N/m^2

100 pascals = 100 N/m^2

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered
