 Consider a system of two particles : To demonstrate the tremendous acceleration of a top fuel drag racer, you attempt to run your car into the back of a dragster that is "burning out" at red light before the start of a race. (Burning out means spinning the tires at high speed to heat.. Find the value of the cart : The position of an air-track cart that is oscillating on a spring is given by the equation x = 12.4 cos[(6.35 s-1)t] . At what value of t after t= 0.00s in the cart first located at x = 8.47 cm ? The ball will move horizontally as it passes through hoop : A 310 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 28.0 m/s2 for 32.0 s, and then runs out of fuel. Overlook any air resistance effects. Find velocity and acceleration of the cart : The position of a cart that is oscillating on a spring is given by the equation x= 12.3 cm cos [(1.26 s-1)t] .

What coordinate on x axis is the electric field produced : A passenger train is travelling at 31 m/s when the engineer sees a freight train 351 m ahead of his train travelling in the same direction on the same track. The freight train is moving at a speed of 5.6 m/s. What will the period of oscillation of the object : An object that hangs form the ceiling of a staionary elevator by an ideal spring scilliates with a period T. If the elevator accelerates upward 2g , what will the period of oscillation of the object ? How far away did the shell hit : A ball is thrown upward at a speed v0 at an angle of 50.0° above the horizontal. It reaches a maximum height of 7.5 m. How high would this ball go if it were thrown straight upward at speed v0. How fast was he running at first : Find out the constant force that must be exerted on him to bring him to rest in a distance of 1.2 m in a time interval of 0.20 s.opposite the fullback's direction of motion.
