Answer:
a. No, typical small pickup truck springs are not large enough to compress 0.61{\rm m}.
Explanation:
It is calculated that a)The angular velocity of the wheel is 272.13 rad/s,
b)On the edge of the grinding wheel, the linear speed is 47.62 m/s,
and c) On the edge of the grinding wheel, the acceleration is 12958.08 m/s².
Calculation of angular velocity, linear speed & acceleration:
Provided that,
the diameter of the wheel = 0.35 m
So, the radius, r = 0.35/2 = 0.175 m
As 1 revolution = 2π rad
(a)the angular velocity, ω = 2600 rpm = rad/s
⇒ω = 272.13 rad/s
So, the angular velocity is 272.13 rad/s.
(b)The linear speed, v = r * ω
⇒v = 0.175 * 272.13
⇒v= 47.62 m/s
(c)The angular acceleration,
⇒ = 12958.08 m/s²

Answer:
a.=4.78 m/s2
b. the thread will remain vertical
Explanation:
a.
For jet acceleration as you know,
Weight due to gravity given as
F= w =mg
and body movement with acceleration as
F= ma
Its acceleration of plane
b.
For planes attaining constant velocity
a = 0 and tan∅ = 0
so Ф = 0
hence the thread will be remain vertical
