This is a two dimensional kinematics problem from physics. This physics is not calculus based. The question is asking for the skier's launch speed as she jumps off of a 65 degree ramp. In other words I need to find out the horizontal velocity.

A Conical Pendulum, in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.040 kg, the string has length L = 0.90 m and negligible mass, and the bob follows a circular path of circumference 0.94 m. What are (a) the tension in the string and (b) the period of the motion?

a) Astrophysics, astronomers and nuclear physics’: light, mid atomic waves caused by the electrons’ ups and downs inside the atom
b) Tarcísio Brito’s (self-taught scientist): Grand Atom (Universe) divided into three powers: Protons, Electrons and Neutrons. The sun contains the positive power (Protons), but with negative feedback (Electrons) and the Interstellar System contains the negative power (Electrons), but with positive feedback (Protons). Planet Earth is responsible for the Neutrons, acting in order to unbalance positive and negative powers in its limits. Therefore, neutralizes beginning and end. And so energies come from the place where they go to, and go to the place where they came from.

A time-varying net force acting on a 6 kg particle causes the object to have a displacement given by:
x = a + b t + d t^2 + e t^3
where a = 2.1 m
where b = 1 m/s
where d = - 2.3 m/s^2
and e = 0.97 m/s^3
with x in meters and t in seconds

Find the work done on the particle in the first 2 s of motion. answer in J

1) A 50 kg block rests on a horizontal surface. The coefficient of static friction is 0.50. The coefficient of kinetic friction is 0.35. A force P of 250 N is applied as shown:

[]--------->P

First, can we make conclusions given the data? If not, why not? If so, does the block move and continue to move at a constant velocity?

2) A block is placed on a plane whose angle of inclination is 30 degrees. THe coefficients of static and kinetic friction for the block on the inclined plane are both 0.2. The block........

In this case, would the block accelerate down the plane? If not, what does the block do?

3) Two objects are sliding at the same speed across a wooden surface. The coefficient of kinetic friction between the first object and the surface is twice that between the second object and the surface. The distance traveled by the first object before it stops is S. The distance traveled by the second object is:

Would the answer to this be S/2? Why or why not
