Hi I am doing Projectile Motion questions can you please help me, The Activity is on this website here
The question are these
Set velocity to 40 m/s and angel to 20° and gravity to -9.8 and uncheck the drag box check mark.
1) What is the horizontal distance the cannon travels ----> I get 170 meters is that correct
2) Calculate the vertical velocity (V y-axis) of the ball. show the trig steps
-----> I get 13.7 meters is that correct
3) Calculate the howizontal velocity (V x-axis) of the ball. show the trig steps
-----> I get 37.6 meters is that correct
4) Determine the amount of time the ball is in the air
-----> I get 20.7 seconds and I koe its wrong can you please help me
5) If the cannon is 1 m long, and the cannon ball has a mass of 15 kg, what is the force of the gunpowder on the cannon ball
-----> ok? how do i DO this please help and check my answers if they are right
