Kinematics in 2D ? i have a few question can someone help me...thanks in advanced 1. An airplane with a speed of 97.5m/s is climbing upward at an angle of 50.0 degree with respect to the horizontal. When the plane's altitude is 732m, the pilot releases a package. (a) calculate the distance...

1. A cab driver picks up a customer and delivers her 2.00km away, on a straight route. The driver accelerates to the speed limit and, on reaching it, begins to decelerate at once. The magnitude of the decelerates is three times the magnitude of the acceleration. Find the lengths of the...

can some1 help me w/this question...like i don't know where to start...thanks in advance A spring is haning down from the ceiling, and an object of mass m is attached to the free end. The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and...

ok for this one i got an answer of 10.2 m/s...but is wrong...and i don't know why...

ok i think it got it...so w=5.22, r=10.2cm ( do i need to change that into m)...so then i can find ac right? then using ac = v^2/r...i can find the velocity right?

So the new speed will reduces by three too..is that right?

so ac = ω2r to find W...is ac = 2.61Hz and r =0.102m put it into find W then put w in v=wr equation to find V?

2 physics Questions... 1. There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the...

Thank you sooooooooooo much..i figured it out already

More Physics help... Which formulas should i use? thankssssssssss 1. Three forces act on a moving object. One force has a magnitude of 86.3 N and is directed due north. Another has a magnitude of 67.0 N and is directed due west. What must be (a) the magnitude and (b) the direction of the...
