• ### Is this problem impossible to solve using kinematics equation?

I don't see how we can solve it: Car A is traveling east on a straight, level freeway at a speed of 24.0 m/s, and it passes car B, which is initially at rest. At the moment when car A passes it, car B begins to accelerate eastward at a constant rate of 1.37 m/s2. At that same moment, car A begins to slow at a constant rate of 0.58 m/s2.

How much faster is car B going than car A at the moment when B passes A? Seriously, I spent lot's of time looking at different ways to solve it. I got even more confused each time.

A police car at rest, passed by a speeder traveling at a constant 110 km/h, takes off in hot pursuit. The police officer catches up to the speeder in 700 m, maintaining a constant acceleration. a) Calculate the required police car acceleration. b) Calculate the speed of the police car at the overtaking point. A car is behind a truck going 25 m/s on the highway. The driver looks for an opportunity to pass, guessing that his car can accelerates at 1.0 m/s^2, and he gauges that he has to cover the 20 m length of the truck, plus 10 m clear room at the rear of the truck and 10 m more at the front of it. In the oncoming lane, he sees a car approaching, probably also traveling at 25 m/s. He estimates that the car is about 400 m away. Should he attempt the pass? Details and explain.

My problem is this. I would like to propel a foam nerf type football that is a little under 2" in diameter and weighs 1.0 oz out of a plastic tube to a velocity of 275 feet per second. I am trying to size a compression spring that will power this. Ideally the spring would have an outer diameter of 1.94" so it will be guided by the inside of the tube. The spring would be compressed then released to propel the nerf. If I can calculate the required spring rate I could then size the spring wire diameter, length and coils required. Any thoughts would be appreciated.

One end of a uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle theta with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.39 1) Let the angle between the cord and the stick is theta = 16 degrees. A block of the same weight as the meter stick is suspended from the stick, as shown, at a distance x from the wall. What is the minimum value of x for which the stick will remain in equilibrium? 2) When theta = 16 degrees, how large must the coefficient of static friction be so that the block can be attached 13 cm from the left end of the stick without causing it to slip? http://session.masteringphysics.com/prob...

The skateboard takes 8.5 s to travel the 1.0 m distance, and it then coasts for another 1.25 m before coming to rest. Calculate the force applied to the skateboard, and also the constant frictional force opposing its motion." Here's what I did: there's two intervals 1) d=1 m, constant velocity 2)d=1.25 m, "coasting" so negative acceleration I found Fnetx equations for both, plugged 2) into 1) and got Fapp= -ma. I found "a" by finding constant velocity of 1) and using it as V1 in 2). a= - 0055319 it seemed pretty straightforward but in the end I got some crazy number, Fapp=Ff= 0.0028 N. did i do this right? it just seems like an odd number to get. please don't go to the trouble of typing out a complete answer. can someone just look for holes in my process? holey moley physics!
