Question

A ball is thrown vertically upward with an initial velocity

of 29.4 meters
per
second. What is the maximum height
reached by the ball? [Neglect friction.]
O a
29.4 m
O b
14.7 m
O c
88.1 m
O d
44.1 m

Answer 1

D

Step-by-step explanation:

First we define our variables

V0=29.4

a=-9.8

V=0

We have to find the maximum displacement , which I will define as X

We use formula v^2=v0^2+2aX

All we do is substitute our values

0=29.4^2-19.6X

29.4^2=19.6X

X=29.4^2/19.6=44.1
