I'm having trouble
with all four of these.
Given:
Vx= 2.7 m/s
Vy= -1.8 m/s
t= 10.9
From t1=10.9s to t2=24.0s, the average acceleration magnitude = 0.54m/s^2, at 36 degrees measured from the +x axis and +y axis...
I basically got the acceleration for x and y then got their values.
Ax= 0.44
Ay=0.32
Then I got the A sub v-x which equals delta Vx over delta time
so Vx=2.7m/s+(0.44m/s^2)(10)=7.1 m/s
and same for y
Vy= -1.8 m/s + (0.32m/s^2)(10)=1.4
I honestly don't know what I'm doing right now..it's due in like 12 hours argh.
