A body of mass 11.0 kg is traveling at 4.3 m/s along the positive x-axis with no external force acting. At a certain instant an internal explosion occurs, splitting the body into two chunks of 5.5 kg mass each. The explosion gives the chunks an additional 16 J of kinetic energy. Neither chunk leaves the line of original motion. Determine the speed and direction of motion of each of the chunks after the explosion. larger velocity? smaller velocity?

A small object with mass m = 0.0900 kg moves along the +x-axis. The only force on the object is a conservative force that has the potential-energy function U(x)=−αx2+βx3, where α= 9.50 J/m2 and β = 0.300 J/m3. The object is released from rest at small x. A) When the object is at x = 4.00 m, what is its speed? Express your answer with the appropriate units. B) When the object is at x = 4.00 m, what is the magnitude of its acceleration? D) What is the maximum value of x reached by the object during its motion?

PLEASE ANSWER BOTH QUESTIONS! (1) A 2.4 kg particle moves along an x axis, being propelled by a variable force directed along that axis. Its position is given by x = 3.0 m + (4.0 m/s)t + ct2 - (1.8 m/s3)t3, with x in meters and t in seconds. The factor c is a constant. At t = 3.0 s, the force on the particle has a magnitude of 36 N and is in the negative direction of the axis....
