question 15

Multiple Choice

A projectile starts at the coordinate origin, where the displacement vector also originates. The initial velocity, v0, makes an angle θ0 with the horizontal where 0 < θ0 < 90°. At the instant when the projectile is at the highest point of its trajectory, the displacement, velocity and acceleration vectors are A projectile starts at the coordinate origin, where the displacement vector also originates.
