Answer:
a) t = 3.2 s
b) 
Explanation:
a) El tiempo requerido para llegar al suelo se puede calcular usando la siguiente fórmula:
En donde:
: es la altura inicial = 50 m
g: es la gravedad = 10 m/s²
Entonces, el tiempo requerido para llegar al suelo es 3.2 s.
b) La rapidez de la pelota justo antes del choque es el siguiente:
En donde:
: es la velocidad inicial = 0 (dado que se deja caer en resposo)
Por lo tanto, la rapidez de la pelota justo en el momento anterior del choque es -32 m/s (el signo negativo es porque la pelota está cayendo).

Weight equals mass multiplied by the acceleration due to gravity.
Answer:
967500000 years
Explanation:
The Speed at which the radius of the orbit of the Moon is increasing is 4 cm/yr
Converting to m
1 m = 100 cm
The distance by which the radius increases is 3.84×10⁷ m
Time = Distance / Speed
967500000 years will pass before the radius of the orbit increases by 10%.
Answer:
F=mass x acceleration
1000= 2000 x a
a=1000/2000
a=1/2 m/sec^2

Answer:
Explanation:
As we know that backpack is kicked on the rough floor with speed "v"
So here as per force equation in vertical direction we know that
so normal force on the block is given as
now the magnitude of kinetic friction on the block is given as
now when bag is sliding on the floor then net deceleration of the block due to friction is given as
now we know that bag hits the opposite wall at L distance away in time t
so we have
