and the current era
Explanation: Ap3x
Answer:
The magnitude of the hiker’s resultant displacement is 5.6 km
The direction of the hiker’s resultant displacement is 77 degrees south west! Hope this helps!!!
Answer:
Ac = v²/r
where, Ac is centripetal acceleration
v is velocity
r is radius
5 = (20)²/r
r = 400/5
r = 80m
from,
w = 2πf
where, w = angular velocity and f frequency
w = v/r
f = n/T
then,
v = <u>2πrn</u><u> </u>,n = 1 to complete 1 cycle
T
T = 2πr/v
T = 2π*80/20
T = 25.14seconds.
The car would take 25.14s to complete 1 cycle of the roundabout.
Respuesta:
4.9 × 10³ J
Explicación:
Paso 1: Información provista
- Masa del coyote (m): 30 kg
- Velocidad del coyote (v): 65 km/h
Paso 2: Convertir la velocidad del coyote de km/h a m/s
Vamos a usar los siguientes factores de conversion:
65 km/h × (1000 m/1 km) × (1 h/3600 s) = 18 m/s
Paso 3: Calcular la energía cinética del coyote (K)
Usarémos la siguiente fórmula.
K = 1/2 × m × v²
K = 1/2 × 30 kg × (18 m/s)² = 4.9 × 10³ J
