[Q3-Lab•] Make sure the two carts face each other's velcro side so they stick together after the collision. Have one cart stationary and give the other a little push. Watch this video and get data from here (blue cart has the fan). Based on the respective cart recorded speeds: Q3a) Show that within reasonable accuracy limits, the momentum of the system is conserved Q3b) Show that within reasonable accuracy limits, the kinetic energy of the system is not conserved

A block and sphere are connected by a cord that passes over a pulley as shown. Neglect friction and assume the cord is massless. Take m1 = 2.00 kg, m2 = 7.65 kg, and ? = 49.0°. A triangular structure is oriented such that its base rests upon a horizontal surface, its left side is perpendicular to its base, and its right side forms an incline of angle ?. A pulley is attached to the structure's apex. Two objects are connected by a cord that passes over the pulley. A circular object labeled m1 is attached to the to the left end of the cord and hangs freely. A rectangular object labeled m2 is attached to the end of the cord and rests upon the incline. (a) What are the magnitude of acceleration (in m/s2) of the block and sphere? _____m/s2 (b) What is the tension (in N) in the cord? (Enter the magnitude.) ____N (c) What is the speed (in m/s) of each object 2.25 s after being released from rest? ____m/s   (d)What If? If the incline under m2 is rough, what is the minimum value…
