Which of the following settings will allow a projectile to hit a target located 15 meters away? Velocity vector "A" =Vi = 12m/s at 30°

Velocity vector "B" =Vi = 13m/s at 30°

Break down each vector into X and Y components to get the initial vertical and horizontal velocities.

Solve for time in the vertical direction

Solve for distance in the horizontal direction

With an initial speed of 18m/s, target distance of 20m and no air resistance, what angle must the

cannon be at to hit the target

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
