Answer:
Explanation:
Circle motion
Weight=4lb
Radius=3ft
Velocity Vb= 6ft/s
Velocity Vr=2ft/s
Velocity Vo=12
V2=√Vo²+Vr²
12=√Vo²+2²
Square both side
144=Vo²+4
Vo²=140
Vo=11.83ft/s
Applying conservation of angular momentum
Ha1=Hb2
MbVbr1=MbVor2
r2=Vbr1/Vo
r2=6×3/11.83
r2=1.52ft
The require time is written as.
∆r=Vrt
t=∆r/Vr
t=r1-r2/Vr
t=3-1.52/2
t=0.74sec
Angle made by the light ray with the surface of mirror is given as
degree
now as we know as per law of reflection that
angle of incidence = angle of reflection
So here we can say that
now the total angle that reflected ray will rotate with respect to incident ray is known as angle of deviation
so here reflected light will deviate by total angle of 40 degree fron its incident ray.

Explanation:
Another way to perceive this is 1 G = 9.81 Newtons per Kilogram so 50 G =490.5 Newtons per Kilogram. The 100 gram apple at 1 G has 0.981 Newtons of force and at 50 G has an apparent weight of 5 KG or 49.05N.
