Arock is tossed at an initial velocity of 60 m/s at an angle of 10° with the ground. after 0.9 second, how far has the rock traveled horizontally and vertically?

Step-by-step explanation:

In the x direction:

x = x₀ + v₀ₓ t + ½ at²

x = (0 m) + (60 m/s cos 10°) (0.9 s) + ½ (0 m/s²) (0.9 s)²

x ≈ 53 m

In the y direction:

y = y₀ + v₀ᵧ t + ½ gt²

y = (0 m) + (60 m/s sin 10°) (0.9 s) + ½ (-9.8 m/s²) (0.9 s)²

y ≈ 5.4 m

answer: 1 and 3

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
