Question

a ball is thrown downward with an initial velocity of 12m/s force applied

Answer 1

The complete question is as follows :

A ball is thrown downward with an initial velocity of 12 m/s. Using the approximate value of g= 10 m/s2, what is the velocity of the ball 1.2 seconds after it is released?

The solution is as follows :

We will use the following equation of motion :

V = u + at

U = 12 m/s

a = 10

t = 1.2 seconds

Doing the substitution :

V = 12 + 1.2 × 10

V = 12 + 12

V = 24

= 24 m/s
