given that acceleration due to gravity is a = -10 m/s^2

initial speed will be ZERO

and we need to find the displacement in t = 8 s

now we can use kinematics equation to find the displacement

\delta y = v_y * t + \frac{1}{2}at^2

now plug in all values in it

\delta y = 0* 8 + \frac{1}{2}*(-10)*8^2

\delta y = -320 m

<em>so it will displace downwards by 320 m</em>

An object is thrown directly upwards from the ground at a velocity of 9ms. Recalling that the acceleration due to gravity is −gm
olga55 [171]

Answer:

Explanation:

Given

Object is thrown with a velocity of u=9\ m/s

Acceleration due to gravity is -g (i.e. acting downward)

Vertical distance traveled by object is given by

v^2-u^2=2as  

where v=final velocity

u=initial velocity

a=acceleration

s=displacement

at maximum height final velocity is zero

0-(9)^2=2\times (-g)\times (s)

s=\frac{81}{2g}=\frac{40.5}{g}\ m

time taken to reach maximum height

using

v=u+at

0=9-gt

t=\frac{9}{g}\ s
