Un carro de montaña rusa parte del reposo desde una primera cumbre, desciende una distancia vertical de 45 metros y luego sube u
na segunda cumbre, llegando a la cima con una rapidez de 15m/s. ¿Que tan alto está la segunda cumbre? No considere la fricción.

Answer:
0.2 m/s
Explanation:
= Mass of glider A= 0.125 kg
= Mass of glider B = 0.375 kg
= Initial Velocity of glider A = 0 m/s
= Initial Velocity of glider B = 0 m/s
= Final Velocity of glider A = 0.6 m/s
= Final Velocity of glider B
As linear momentum is conserved
Magnitude of the glider B at this time is 0.2 m/s
Answer:
first minimum distance from the center = 0.417 m m
Explanation:
given,
wavelength (λ) = 506 nm
d = 0.075 mm = 0.000075 m
tanθ = x /2
d sinθ = m λ
m=1 ( 1 st minimum )
0.000075 × sin θ = 506 × 10⁻⁹
sin θ =
sin θ = 0.00675
θ = sin⁻¹(0.00675)
θ = 0.00675
x = 0.000417 m
hence, the first minimum distance from the center = 0.417 m m
