1. Professional golfer Lopez hits a golf ball with a force to produce an initial velocity of 175 feet per second at an angle of 35 above the horizontal. She estimates the distance to the hole to be 225 yards.
So I made my parametric equations
x= T 175cos(35)
y= T 175sin(35)-16t^2
Find the range of the ball? How would I find the range of the ball?
2. Alfredo is performing a physics experiment in which he will launch a rocket the rocket is supposed to release a parachute 300 feet in the air 7 seconds after liftoff. He is firing the rocket at 78 degrees from the horizontal.
I know the initial velocity is 158.31 ft/s using my parametric equation
Now it ask me "to protect other students from falling rocket the teacher need to place warning sings 50 yards from where the parachute is released. How far should the sings be from the point where the rockets are launched"?
How would I figure this out.
Can anyone show me how to these two problems
