A solid of mass 8kg at a temperature of 120 degree Celsius is dropped into a calorimeter containing water of Mass 15kg at a temperature of 12 degree Celsius . 1. calculate the temperature of the mixture. Cw= 4200J/Kg/K CS= 720k/J/Kg

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?
