y=y0 v0t-gt^2/2

How to solve these kinematics problems:

1) Identify what you know

time = 1.5s

acceleration due to gravity = 9.8m/s^2

initial height = x0 = 0m

initial velocity = v0 = 0m/s

2) Identify what you dont know

height (x)

y=0 0-9.81*1.5^2/2=-11.04 m (or positive if you flip your axis)

4) Plug in what you know and solve:

x = 0 0*t (1/2) * (-9.8) * (1.5)^2

x = -11.025 m

4) Plug in what you know and solve:

x = 0 0*t (1/2) * (-9.8) * (1.5)^2

x = -11.025 m

4) Plug in what you know and solve:

x = 0 0*t (1/2) * (-9.8) * (1.5)^2

x = -11.025 m

Dont ask twice nextime but wait for ppl.(an space the time btw which u ask a question)

V=u gt note g can be 10 or 9.8 but I used 10 since it is the general one.

V=0 10*1.5 = V=15 0=15m/s

V^2=u^2 2gh

15^2-=0^2 2*10*S

225=20s

S=225/20=11.25m=11.3m
