a car travel at a constant acceleration of 5 m/s2 from rest. How long will it have traveled by the time it reaches a velocity of 80km/h?​

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

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%)

What is the magnitude of the resultant vector round your answer to the nearest tenth
