7) Farah and Athena were attempting to push Kieran on the scooter with enough force so that Kleran would run into Mr. Collins. They figured out they needed a 50 N force to run the scooter into Mr. Collins, Farah and Athena were both applying
force from the left, Farah
applying a 20 N force and Athena pushing with a force of 15 N. Were they able to get Kleranto
run into Mr. Collins? How can they get it to hit him?

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?

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.
