Question

A ball with a diameter of your last digit of your University ID+1) cm leaves a girl's hand with an upward velocity of 6 meters per second. What is the maximum height of the ball above the girl's hand? neglect air resistance Select one: a. 6.4 M b. 1.8 M C. 7.0M 0 d. 4.5 M e. 5.2 M 0 0 g. 12 M HOM

Answer 1

Given data:

U = 6 m/s

Using the equation of motion,

$V^2-U^2=2gH$

Where,

Velocity at maximum height V = 0

$g=-9.81\:m/s^2$

from the equation,

$0-6^2=2\times-9.81\times H$

Maximum height attained by the object,

H = 1.8 m
