1. The problem statement, all variables and given/known data I have a problem worksheet for my 'Physics A' class. It deals with 1-D Kinematics, which we are just getting into so im not very sure what equations I need to use. I'm not asking for someone to answer them for me, but to maybe give me a list of a few equations that would help me answer my problems. A few examples that I have are: An engineer is to design a runway to accommodate airplanes that must gain a ground speed of 61.0 m/s before they can take off. If these planes are capable of a uniform acceleration of 1.50 m/s2 a) how long will it take them to achieve take-off velocity;b) what must be the minimum length of the runway? OR A stone is dropped from an airplane at an altitude of 4.90*102 m. The stone required 10.0 s to reach the ground. At what rete does gravity accelerate the stone? OR A driver of a car going 90.0 km/h N, suddenly sees the lights of a barrier 40.0 m ahead. It takes the driver 0.750 s to apply the brakes, and the maximum acceleration during braking is 10.0 m/s2 S. Determine if the car hits the barrier. 2. Relevant equations I just need basic equations. How to find how long it will take something to fall, or how to find the acceleration or velocity. 3. The attempt at a solution The only solutions I was able to find were the simple ones that I could do in my head. Q. A boy walks 13.0 km in 2.0 h. What is his speen in km/h? A. 6.5 km/h. OR Q. On a baseball diamond, the distance from home plate to the pitcher's mound is 18.5 m. If the pitcher is capable of throwing a ball at 38.5 m/s, how much time does it take a ball to reach home plate? A. 0.481 s.
