1.-) Se procede a realizar a lanzar ciertos objetos por medio de un equipo apoyado en el piso con un ángulo de inclinación de 45o , siendo disparados con una velocidad inicial de 180 km/h. Cuál sería la altura máxima alcanzaran los platos?

2.-) Se lanza unas pelotas con un disparador que tiene un ángulo de inclinación de 75o y con una velocidad de 25 m/s. Calcular:

a.) La altura máxima que alcanza las pelotas.

b.) El tiempo de vuelo que permanece en el aire.

c.) El alcance horizontal a que se caerían las pelotas al piso.

3.-) Un Objeto es lanzado y realiza un movimiento parabólico con una velocidad inicial de 85 m/s y un ángulo de 65o , Calcular el tiempo de vuelo del objeto lanzado.

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3
