We had a lab on projectile motion and one of the questions was this:
Use your Vy versus t graph to determine the y-component of the acceleration of the puck. Should this be equal to the acceleration due to gravity (9.8 m/s)? Explain why it is or why it is not.
The acceleration we got from the Vy vs time graph is -1.90m/s^2. Should that have been the same with -9.8 m/s^2? Also just take note that the object was launched at a certain angle.
The Attempt at a Solution
My answer is no because the platform at which the object was thrown was launched at an angle (?) I really can't explain it.
