1. A daredevil on a motorcycle leaves the end of a ramp with a speed of 35 m/s. If his speed is 33 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance.
I don't know how to approach this problem or set it up? Do I use...
Here are a couple problems that I have been attempting to do but I am not sure if I am doing them right.
1. A block of mass 2.50 kg is pushed 2.20 m along a frictionless horizontal table by a constant 16.0-N force directed 25 degrees below the horizontal. Determine the work done by (a) the...
Here is the problem. I think I set it up right but I am stumped now.
An object with mass m1=5.00 kg rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2=10.0 kg. Find the acceleration of each object...
Thanks for your help. I really appreciate it.
I got 6.62 m/s for part A and used V=Vo+at to get -.45m/s^2 on part B.
I hope this is correct. I'm pretty sure A is.
Can anyone confirm?
A truck covers 40.0 m in 8.50 s while smoothly slowing down to a final speed of 2.80 m/s. (a) Find the truck's original speed. (b) Find it's acceleration.
I used the 2nd formula originally (X=VoT+1/2aT^2) but I wasn't getting anywhere. Can someone point me in the right direction on how to do...
I am in my first physics class and the professor just kinda skimmed over this but I am lost on how to convert km/h to m/s.
What's the explanation on how to convert 82.4 km/h to m/s?
Thanks in advance for any help.
I just transferred to UMD and want to do well in this course because I need a C or better to get into my major (Psychology). So any help on the problem would be much appreciated. I got through most of them fine except this one. I am stumped. :-p
1. Runner A is initially 4.0 mi west of a...
