Three people are standing on a horizontally rotating platform in an amusement park. one person is almost at the edge, the second one is (3/5)r from the center, and the third is (1/2)r from the center.

1-if the period of rotation of the first person is t1 = t, find in terms of tthe period of rotation of the second person.

2- if the period of rotation of the first person is t1 = t, find in terms of t the period of rotation of the third person.

3-if the speed of the first person is v1 = v find in terms of v the speed of the second person

4- if the speed of the first person is v1 = v find in terms of v the speed of the third person.

5- if the radial acceleration of the first person is a1 = a, find in terms of athe radial acceleration of the second person.

6- if the radial acceleration of the first person is a1 = a, find in terms of athe radial acceleration of the third person.

1134567 a jet with mass m = 1.1 ă— 105 kg jet accelerates down the runway for takeoff at 2 m/s2. 1) what is the net horizontal force on the airplane as it accelerates for takeoff? 2.2*10^5 n your submissions: 2.2*10^5 computed value: 220000submitted: saturday, january 26 at 2: 41 pm feedback: correct! 2) what is the net vertical force on the airplane as it accelerates for takeoff? 0 n your submissions: 0 computed value: 0submitted: saturday, january 26 at 2: 41 pm feedback: correct! 3) once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 21 m/s, while the horizontal speed increases from 80 m/s to 95 m/s. what is the net horizontal force on the airplane as it climbs upward? n 4) what is the net vertical force on the airplane as it climbs upward? n 5) after reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 13 seconds. what is the net horizontal force on the airplane as it levels off? n 6) what is the net vertical force on the airplane as it levels off?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
