Answer:
Los datos que tienes son:
m = 13 kg
d = 46 m
∪ = 0,45
g = 9,8 m/s²
Fr = ?
w = ?
Lo primero que haremos que calcular Fr
Fr = ∪mg
Fr = (0,45) (13 kg) (9,8 m/s²)
Fr = 57,33 N
Calculamos el trabajo realizado.
w = Fd
w = (57,33 N) (46 m)
w = 2637,18 Joules
Respuesta.
El trabajo realizado es 2637,18 Joules
Explanation:
Answer:
The time taken for the airplane to cover the distance is 15 minutes.
Explanation:
Given;
velocity of airplane, u = 800 km/h
distance traveled by the airplane, s = 200 km
The time of this motion is given by;
s = ut + ¹/₂at²
at constant velocity, acceleration, a = 0
s = ut
t = s / u
t = (200 km) / (800 km/h)
t = 0.25 hour = 15 mins
Therefore, the time taken for the airplane to cover the distance is 15 minutes.
