Some kids are playing dodgeball, in which they throw squishy balls at each other while trying to avoid being hit themselves. assuming that the collisions between the balls are inelastic, which of the following statements is true if two balls collide with each other? a. neither the kinetic energy nor the momentum of the system is conserved. b. the momentum of the system is conserved, while kinetic energy is not conserved. c. the kinetic energy of the system is conserved, while momentum is not conserved. d. both the kinetic energy and the momentum of the system are conserved.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.

Check the following equation for dimensional homogeneity: ⅆ mv=∫t1t2(f⁢cosθ)ⅆt where m is mass, v is velocity, f is force, θ is an angle, and t is time. check that each term in the equation has the following dimensions: [malbec] where you are to choose the coefficients a, b, c.
