Answer:

Option (c) is the correct choice, as it indicates the object will cover 1.6 m

Explanation:

We are informed that the conveyor runs at a velocity of u = 3.1 m/sec

The robot's mass is 10 kg

with a static friction coefficient of 0.5 and a kinetic friction coefficient of 0.3

Acceleration due to gravity is g = 9.8 $m/sec^2$

The acceleration a is calculated as kinetic friction coefficient multiplied by g, that is, a = 0.3×9.8 = 2.94 $m/sec^2$

$v^2=u^2+2as$ According to the third motion equation

$0^2=3.1^2-2\times 2.94\times s$

Ultimately, the conveyor’s velocity reaches zero

Therefore,

s = 1.6 m

[[TAG_39]]Thus, option (c) stands as the correct option[[TAG_40]][[TAG_41]][[TAG_42]]

Answer:

The plane's speed in relation to the ground is 300.79 km/h.

Explanation:

Provided details include:

Wind speed = 75.0 km/hr

Plane's airspeed = 310 km/hr

Next, we must find the ground speed of the plane

Calculating the angle

Using the angle formula

$\sin\theta=\dfrac{v'}{v}$

Where v' represents the wind speed

v represents the plane's speed

We will substitute the values into the formula

$\sin\theta=\dfrac{75}{310}$

$\theta=\sin^{-1}(\dfrac{75}{310})$

$\theta=14.0^{\circ}$

Now, we must find the resultant speed

Using the resultant speed formula

$\cos\theta=\dfrac{v''}{v}$

Insert the values into the formula

$\cos14=\dfrac{v''}{310}$

$v''=\cos14\times310$

$v''=300.79\ km/h$

Consequently, the plane's speed in relation to the ground equals 300.79 km/h.

1200 N-m of torque is used to drive a gear (A) of diameter 25 cm, which in turn drives another gear (B) of diameter 52 cm. What

Ostrovityanka [3204]

Response:

2.5kN.m

Details:

Torque relates directly to the pitch diameter

= Ta/Tb= Da/Db

For 120/Tb= 0.25/0.5

This gives Tb= 2.469kN.m, roughly 2.5kN.m
