Slide on! A block placed on an incline oriented 42°
with respect to the horizontal has velocity
13.4 [m/s] î – 12.0 [m/s] j at time t = 0.00
[s]. If its acceleration is
a = 0.706 [m/s²]i – 0.636 [m/s²]j, what is the
velocity v after t = 15.0 [s]?
u =
O 24.0 [m/s] i – 21.5 [m/s] j
O 24.0 [m/s] î – 9.54 [m/s] ĵ
O 3.86 [m/s] î – 1.41 [m/s] j
O 10.6 [m/s] î – 21.5 [m/s] ĵ
