Answer:
Height as seen by the professor = 38.2 m
Explanation:
Angle of throw = θ = 69°
Velocity of throw = v
X component of velocity = v₁ = v cos 69 = 0.3584 v m/s
Vertical component of the velocity = v₂ = v sin 69 = 0.9336 v m/s
v₂ / v₁ = tan 69 = 2.605
v₂ = 2.605 v₁.
Professor sees as if the x component of velocity =0
v (as seen by professor) + v' = 0
=> v as seen by professor = -v' = -10.5 m/s
This shows that y component of the ball's velocity is 2.605 times its x component of velocity.
with respect to the professor, there is only y component of velocity.
v₂' =v₂ = 2.605 ( -10.5) = 27.4 m/s.
Height as seen by the professor = (27.4)² / 2(9.8) = 38.2 m
Answer:
well at the rate he goes he would be at 2.5km
B). Developmental psychology and counseling psychology
Answer:
It is given that the weight of the person is 102 N
We have the force that shall be needed to being the man out in minimum amount of time shall correspond to the maximum tension that can be developed
Thus using Newton's second law we obtain the acceleration that the man shall attain
Now using second equation of kinematics to obtain time 't' we get
