If the vertical initial speed of the ball is 2.0 as the cannon moves horizontally at a speed of 0.65 , how far from the launch point does the ball fall back into the cannon?
Did you provide all information provided by this question? Also, your units are missing.
oops sorry. A wheeled car with a spring-loaded cannon fires a metal ball vertically. If the vertical initial speed of the ball is 2.0 m/s as the cannon moves horizontally at a speed of 0.65 m/s, how far from the launch point does the ball fall back into the cannon?
Okay, use kinematic equations. Make sure to separate into horizontal, vertical components.
I tried using those equations. 0=0+2.0t-4.9t^2 From this I used the quadratic formula to find t and I keep getting negative answer that isn't right.
sorry for the time. Back now. So here is how I'd do it...|dw:1360798976282:dw|
