A train travelling at 20m/s undergoes a uniform deceleration of 2m/s2 when brakes are applied.. calculate the time taken to come
VLD [36.1K]

Answer:

a) 10 seconds

b) 100 meters

Explanation:

<u>Accelerated Motion </u>

If an object is moving at contant speed, we know it has zero net force applied. As soon as an unbalanced force appears, the object accelerates (positive or negative) depending on the direction of the force with respect to movement. The speed of an object subject to acceleration is given by

v_f=v_o+at

The distance traveled is given by

\displaystyle x=v_ot+\frac{at^2}{2}

a)

Our train is travelling at 20m/s when it decelerates at -2\ m/s^2 (negative for it's against movement). If nothing else happens, it will eventually stop (v_f=0). We can compute the time at which it happens :

\displaystyle t=\frac{v_f-v_o}{a}

Knowing\ v_f=0

\displaystyle t=\frac{-20}{-2}=10\ sec

b)

The distance traveled is

\displaystyle x=v_ot+\frac{at^2}{2}

\displaystyle x=(20)(10)-\frac{2(10)^2}{2}

\displaystyle x=100\ m

A person is sitting with one leg outstretched and stationary, so that it makes an angle of θ = 27.5° with the horizontal, as the
dangina [55]

here we will use the torque balance about the knee joint

here we can say that

\tau_g = \tau_m

here torque due to weight is given as

\tau_g = 40.1 cos\theta*(l_1 + l_2)

\tau_g = 40.1 cos27.5*(0.105 + 0.150)

\tau_g = 9.07 Nm

now torque due to applied force of muscle

\tau_m = M*sin\alpha * l_1

\tau_m = M*sin30* 0.105

now by torque balance we will have

9.07 = M*0.5*0.105

M = 173 N

so here the magnitude of m will be 173 N

What is the voltage in a circuit if the current is 6.2 A and the resistance is 18 ohms?
Nitella [24]
We already know the formula:
Voltage = Current * Resistance
In the given question, there are numerous information's that are already given.
Current = 6.2 A
Resistance = 18 ohms
Then
Voltage = 6.2 * 18 Volts
             = 111.6 Volt
So, the voltage in the circuit will be 111.6 volts. I hope it helps you.
