We know, F = m*a
Here, F = 600-400 = 200 N downwards
m = 60 Kg
Substitute their values,
a = 200/60
a = 20/6
a = 10/3
a = 3.33 m/s² downwards
In short, Your Answer would be 3.33 m/s² downwards
Hope this helps!
Explanation:
a) Given in the y direction (taking down to be positive):
Δy = 50 m
v₀ = 0 m/s
a = 10 m/s²
Find: t
Δy = v₀ t + ½ at²
50 m = (0 m/s) t + ½ (10 m/s²) t²
t = 3.2 s
b) Given in the x direction:
v₀ = 12 m/s
a = 0 m/s²
t = 3.2 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (12 m/s) (3.2 s) + ½ (0 m/s²) (3.2 s)²
Δx = 38 m
Usually in the deep sea and underwater caves where there is no light

<span>In general, as you move across a row in the periodic table, B. atomic radius decreases.
This is because there is a stronger attraction between outermost electrons and nucleus, which is why the radius between them becomes smaller.
