For a projectile motion, the angle between the velocity and acceleration is minimum and acute at

Options

  1. Aonly one point
  2. Btwo points
  3. Cthree points
  4. Dfour points

Correct answer

A. only one point

Step-by-step solution

In projectile motion, centre of acceleration is directed towards the centre of earth and at peak point, the angle between velocity and acceleration is 90^ . because at peak point the vertical component of velocity is zero. Thus, it is minimum and acute at only one point (i.e. at heighest point)
