Cho hệ số cơ như hình 5 thanh m chuyển động thẳng đứng nhờ khe cô định. Khối lượng thận và nêm là m=M=1kg, a = 30° lấy g = 10m/s^2. Bỏ qua mọi ma sát. Tìm gia tốc của nêm M

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

According to newton’s first law of motion, which force is expected to cause a body to accelerate?
