Question

A 1.0 kg ball is thrown into the air and initial velocity of 30 mi./s how high into the air did the ball travel

Answer 1

45.9m

Step-by-step explanation:

Given parameters:

Mass of the ball = 1kg

Initial velocity = 30m/s

Unknown:

Height the ball will travel = ?

Solution:

At the maximum height, the final velocity of the ball will be 0;

Using ;

V² = U² - 2gh

V is the final velocity

U is the initial velocity

g is the acceleration due to gravity

h is the height

0² = 30² - (2 x 9.8 x h)

0 = 900 - 19.6h

h = 45.9m
