SOLUTION
Name - Mortada Ali
Qassem
Ya = (y»)o +(v»)ot – g²
with (yg)o =0, (vg)o =3 m/s, and g =9.81 m/s².
YB = 3t – 4.9051²
The elevator undergoes uniform motion.
YE = (yg)o +Vgt
with (y,), =-10 m and v, = 4 m/s.
(a)
Time of impact.
Set yn = Yɛ
31 – 4.9051² = -10+41
4.9051² +1 – 10 = 0
t = 1.3295 and -1.5334
t = 1.330 s
(b)
Location of impact.
YB = (3)(1.3295)-(4.905)(1.3295)² =-4.68 m
YE = -10+(4)(1.3295) = -4.68 m
(checks)
4.68 m below the man
Hey I want a nice
handwriting please
with my name the
same solution
