finding Ux and Uy (1 Viewer)

[2671library]

If I'm given
∆x = 300m
∆y = 150m
t = 21 seconds
a = -1.6ms-2

What are my values for
Ux and Uy?

 

[Squar3root]

Ux= 300/21

 

[Squar3root]

-150 = 21Uy -0.5*1.6*21^2

 

[Squar3root]

iirc

Thank you, If I than have
Ux = 14.29ms-1
Uy = 9.66ms-1
∆y = 150m
a = -9.8ms-2

What is the value for ∆x and t?

Nah it's from the top of a 150m cliff

Nah it's from the top of a 150m cliff

oh its a different case then lol

 

[Parvee]

Ux= 300/21

this is assuming t=21 is time of flight

-150 = 21Uy -0.5*1.6*21^2

this is assuming t=21 is time to max height


so one of them is incorrect irrc
or maybe im just derping

 

[2671library]

t is the time of flight

nah you're right; OP just gave some random values and I assumed s/he cbf'd typing the question and/or subbing it into the formula so one of them is right

if this starting and finishing on the ground? or from a cliff?

Is the max height of the projectile given?

Post the whole question.
