I have 2 problems that I am completely stuck on. I have tried to solve them, but just can't. I am working on summer homework for AP Physics B and I am stuck on these 2.
The vertical leap of a professional NBA athlete is reported to be 47.3 inches. What is his takeoff speed?
displacement=47.3 inches since it is the leap
can't find any
I do not know what to do. I assume that the takeoff speed is the initial velocity, but I do not know any time values. These time values are needed for any equation I could use to solve this.
Second problem
A hot air balloon is descending at a rate of 2.6 m/s when a passenger drops a camera.
If the camera is 45 m above the ground when it is dropped, how long does it take for the camera to reach the ground?
displacement= 45m since the camera has to be dropped
displacement= initial velocity(time)+(1/2)(a)(time^(2))
I assume initial velocity is 2.6. And the time is what has to be solved. I can't figure out what acceleration is though.That is what I need to know.
