Well we (me and the girl who are studying together) we have the answer... and we can get the answer but we don't understand why.
We used F=ma to find the force using the initial velocity and did the same thing using the second velocity and added them together. We come up with the correct...
A 536 g ball stricks a wall at 15.8 m/s and rebounds at 13.1 m/s. The ball is in contact with the wall for 0.038 s.
What is the magnitudue of the force acted on the ball during the collision?
Hi! Thanks for your quick relpy! As soon as I hit submit I actually figured out the problem! I just found the time it would take to his the ground and used that to plug it into the equation to find the displacement of x! I guess just thinking about it as I was typing helped, hehe. Thanks!
Package dropped from a plane!
A plane is flying horizontally with wpeed 281 m/s at a height 3200m about the ground. The acceleration of gravity is 9.8 m/s2. Neglecting air resistance, what is the horizontal distance from the release point to the impact point?
I'm not sure where to start ...
