Question

Projectile Motion 2D

A batter hits a ball with initial speed 20m/s at a launch angle of 60

Answer 1

For two dimensional motion:

In the horizontal, the x position is:

We can consider the starting point as the origin so x₀ = 0

In the vertical, the y position is:

again We  can consider the starting point as the origin so y₀ = 0

The position of the ball will be:

From the image

so the position of the at time t is:

for t = 2,00 s

using g = 10m/s²

and v = 20m/s

remember:

We get:
