Por favr, necesito ayudaa con estos ejercicios de fisica:(( a) Un avión tarde 52 min en llegar de caracas a otra ciudad, si si velocidad es constante y de 295 km/m. Calcular distancia recorrida.
b) Que tiempo tarda un móvil en recorrer 3265 Hm, si su velocidad constante es de 95 m/s?
c) Un carro recorre 936m en 26 min. Expresar su velocidad en Km/h

a) distance = 15340 km

b) time = 3437 seconds

c) velocity = 2.16 km/h

Explanation:

a) If the plane's speed is 295 km/m  and it takes 52 minutes to get to its destination, then we can calculate the distance travelled via the distance formula:

Distance = v * t

and since the time units are both the same in the quantities to multiply (km/minute and minutes travelled), then they cancel out and the distance results in Km:

Distance = 295 * 52 = 15340 km

b) For this problem we need to convert Hm (hectometers) into meters in order to be able to simplify the units appropriately when using the distance formula.

recall that 1 Hm - 100 meters, then 3265 Hm = 326500 m

Distance = v * t

326500 = 95 * t

solving for "t":

t = 326500 / 95

t = 3437 seconds

c) In this problem, we need to convert the distance from m to km, and the time from min into hours in order to give the answer in the requested units. We also use the distance formula we have been using so far,

936 m = 0.936 km

26 min = 26/60 h

Then the magnitude of the velocity becomes:

v = Distance / time = 0.936 / (26/60) ≈ 2.16 km/h

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
