g A small car travels up the hill with a speed of v = 0.2 s (m/s) where s is the distance measured from point A in meters. Deter
jasenka [17]

Answer:

The magnitude of the acceleration of the car when s = 50\,m is 2\,\frac{m}{s^{2}}.

Explanation:

The acceleration can be obtained by using the following differential equation:

a = v \cdot \frac{dv}{ds}

Where a, v and s are the acceleration, speed and distance masured in meters per square second, meters per second and meters, respectively.

Given that v = 0.2\cdot s, its first derivative is:

\frac{dv}{ds} = 0.2

The following expression is obtained by replacing each term:

a = 0.2\cdot 0.2\cdot s

a = 0.04\cdot s

The magnitude of the acceleration of the car when s = 50\,m is:

a = 0.04\cdot (50\,m)

a = 2\,\frac{m}{s^{2}}

An object with a mass of m = 122 kg is suspended by a rope from the end of a uniform boom with a mass of M = 74.9 kg and a lengt
creativ13 [48]

The horizontal rope is under 7,019.4 N of tension.

The pulling force conveyed axially by a string, cable, chain, or another similar device, or by the ends of a rod, is referred to as tension.

The action-reaction pair of forces acting at the ends of the element can also be referred to as tension.

The tension unit is the Newton.

the horizontal rope is tense.

The following formula is used to determine the horizontal rope's tension:

Apply the torque principle;

Mg (L/2) sin + mg L sin = T(L/2) cos

M + 2mg sin/cos = T

(M + 2m)g tan = T

let θ = 66⁰ (The question should include this value)

(M + 2m)g tan = T

T = (74.9 + 2 x 122)(9.8) (tan 66)

T = 7,019.4 N

7,019.4 N is the tension in the horizontal rope.

A uniform disk of mass m = 2.4 kg and radius R = 25 cm can rotate about an axle through its center. Four forces are acting on it
Zinaida [17]

Answer:

0 Nm

Explanation:

Torque is the cross product of the radius vector and the force vector.

τ = r × F

In other words, the magnitude of the torque is equal to the magnitude of the radius times the magnitude of the force times the sine of the angle between them.

τ = rF sin θ

Since F₃ is parallel to the radius vector, θ = 0, so τ = 0.
