A student throws a baseball upwards at an angle of 60 degrees to the horizontal. The initial horizontal and vertical components are 12.5 m/s and 21.7 m/s, respectively. What position will have the greatest magnitude of vertical acceleration

All positions have constant acceleration

Explanation:

Projectiles have two velocity component; a vertical velocity and a horizontal velocity. The horizontal velocity is constant while the vertical velocity is acted upon by the force of gravity, causing a change of vertical velocity.

If the air resistance is negligible, the acceleration of a projectile would be constant and equal to the acceleration due to gravity. This means that the acceleration for a projectile is the same at every point in its trajectory.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
