An object of mass m= 1.00 kg is moving initially with a speed of 2.0 m/s along positive x- direction, makes glancing collision with another object of the same mass, initially at rest. After collision first object moves with a speed of 1.00 m/s at angle of 60.00 with respect to positive x- axis. Determine the speed and direction of motion of second object.
A styrofoam cooler (k = 0.030 W/(m·K)) has outside dimensions of 0.270 m by 0.230 m by 0.280 m, and an average thickness of 2.6 cm. About how long would it take for 1.60 kg of ice at 0 °C to melt in the cooler if the outside temperature is 30.0 °C..
