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

a straight line sloped

b. false

no

explanation:

no i dont know how to solve this you should probably try to google the answer
