Question

A boy throws a ball with a mass of .20kg. Straight up into the air with an initial speed of 15 meters per second. How high does the ball rise? The gravitational constant is 10 meters per second squared.

Answer 1

Answer:

7.2mtrrrrrrrrerreerrrrrrrrrrrrrd

Answer 2

Answer:

I will tell you

Explanation:

u=15m/s

v=0m/s ( because ball stop at one time)

g= -10m/s2 because you throw it upward

formula

s=v^2-u^2÷2g

0^2-15^2÷2×10

-225÷(-20)

= 11.25 m
