A cute robot is automatically rolling off the tabletop with an initial speed of 25.0 m/s. In 5 seconds, how far does it travel (a) vertically and (b) horizontally?
v0x=25 (m/s)v_{0x}=25\ (m/s)v0x=25 (m/s)
v0y=0 (m/s)v_{0y}=0\ (m/s)v0y=0 (m/s)
(a)
y=v0yt+gt22=0⋅5+9.8⋅522=122.5 (m)y=v_{0y}t+\frac{gt^2}{2}=0\cdot5+\frac{9.8\cdot 5^2}{2}=122.5\ (m)y=v0yt+2gt2=0⋅5+29.8⋅52=122.5 (m)
(b)
x=v0xt=25⋅5=125 (m)x=v_{0x}t=25\cdot5=125\ (m)x=v0xt=25⋅5=125 (m)
