Question

A projectile is an object projected in to air with a Initial velocity v0 so that it is moving under the influence of gravity a) What is the shape of the path of projectile b) As a projectile moves in its path , is there any point along the path where the velocity and acceleration vectors are perpendicular to each other c) If E is energy with a projectile is projected . (i) What is the Kinetic energy at the highest point? (ii) What is P.E at highest point?​

Answer 1

Answer:

a) The shape of trajectory is Parabola

b) At maximum height

c) i) K.E at highest point is K.E = $\frac{1}{2}$ mv₀²cos²θ

  ii) P.E at the highest point = $\frac{1}{2}$ mv₀² sin²θ
