Starting with an initial speed of 6.01 m/s at a height of 0.352 m, a 2.61-kg ball swings downward and strikes a 4.18-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 2.61-kg ball just before impact. (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 2.61-kg ball just after the collision. (c) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 4.18-kg ball just after the collision. (d) How high does the 2.61-kg ball swing after the collision, ignoring air resistance? (e) How high does the 4.18-kg ball swing after the collision, ignoring air resistance?

Answer in 3 decimal places Two animals were placed on both end of a hydraulic lift system as show below. A mouse with a mass of m=9 g is placed on a smaller piston with a diameter of 10 cm. If an elephant with a mass of 4 000 kg is placed on the larger piston, how wide should the diameter of the larger piston be so that pressures at both ends are equal?

pls help me i dont know how to do this
A gas filled in a piston-cylinder arrangement as shown in Figure 1 has a volume of 0.09 m³ at its initial equilibrium state. The gas is slowly heated through the bottom of the cylinder that allowed for the gas to expand at constant-pressure of 2095 kPa to a volume of 1.23 m°. The change in internal energy of the gas is 0.24 kJ. Ignoring the friction between the piston and the cylinder and assuming the atmospheric pressure any value from 90 to 110 kPa, of (a) Calculate the mass of the piston if the area of the piston is 0.047 m2 (b) For the gas as a system, evaluate work and heat transfer, each in kJ (c) For the piston as a system, evaluate work and change in potential energy, each in kJ Piston Gas
