If a bearing needs 4. 0 s to solidify enough for impact, how high must the tower be?.
In order to determine the height of the tower, we would apply the second equation of motion and assume that the downward motion is negative.
Mathematically, the second equation of motion is given by this formula:
S = ut + ½gt²
Where:
S represents the distance or height.u represents the initial velocity.a represents the acceleration.t represents the time.Substituting the given parameters into the formula, we have;
S = S₀ + ut - ½gt²
0 = S₀ + (0)4.0 - ½ × (9.8) × 4.0²
0 = S₀ - 4.9 × 16.0
Height, S₀ = 78.4 meters.
How to calculate the bearing's impact velocity?In order to calculate the bearing's impact velocity, we would apply the first equation of motion:
V = u - at
V = 0 - 9.8(4.0)
Impact velocity, V = 39.2 m/s.

I'm having trouble with picking the correct equations for this. Some ways equal 12.4 N-m, but that's wrong. 24.8 N-m is also wrong. I have 62sin60 and 62cos60, and the perpendicular should be 200mm.
The couple of the moment of the two forces is 3.82 N.m
What is the Moment of the Couple?
We are given;
Force applied at A; F_a = 62 N
Force applied at C; F_c = 62 N
AB = BC = 200 mm = 0.2 m
Horizontal component of F_a is; F_ax = 62 cos 50
Vertical component of F_a is; F_ay = 62 sin 50
Horizontal component of F_c is; F_cx = 62 cos 50
Vertical component of F_c is; F_cy = 62 sin 50
Taking moments about point C gives;
M_c = F_ay * AB - F_ax * BC
M_c = (62 sin 50 * 0.2) - (62 cos 50 * 0.2)
M_c = 23.75 - 19.93
M_c = 3.82 N.m

A motorcycle patrolman starts from rest at A two seconds after a car, speeding at the constant rate of 120 km/h, passes point A. If the patrolman acceler- ates at the rate of 6 m/s² until he reaches his maxi- mum permissible speed of 150 km/h, which he maintains, calculate the distance s from point A to the point at which he overtakes the car.
The distance, s from point A to the point at which he overtakes the car is 912 meters.
What is the formula for calculating the distance?Distance may be defined as the total movement of an object without any regard for direction. It is a type of scalar quantity. The formula for calculating the distance is as follows:
Distance = speed/time taken.According to the context of this question,
The speed of motorcycle patrolman = 120 km/h = 120 × 5/18 = 33.33 m/sec.
The maximum permissible speed = 150 km/h = 150 ×5/18 = 41.66 m/sec.
So, at the speed of 6 m/s², it takes 6.94 seconds.
The distance traveled in 6.94 sec = 1/2 (6)[tex](6.94)^2[/tex] = 144.67 m.
So, the cop overtakes the car when at,
33.333t = 144.67 + 41.666(t-2-6.9444)
t = 27.362 seconds.
Now, the distance, s from point A to the point at which he overtakes the car = car(27.362) = 33.333*27.362 = 912m.
Therefore, the distance, s from point A to the point at which he overtakes the car is 912 meters.
