What is the acceleration of a 10 kg mass pushed by a 5 N force

The formula is a = F m so in this case a = 5 10 = 0.5 m s 2

Explanation:

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

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
