A puck sliding on ice approaches a 20 degrees ramp at 10 m/s with coefficient of friction 0.2. How high will it go up the ramp a
timama [110]

Answer:

it will go up along the inclined plane by d = 9.62 m

Explanation:

As we know that puck is moving upward along the slide

then the net force opposite to its speed is given as

F_{net} = - mgsin\theta - \mu mgcos\theta

so here deceleration is given as

a = -g(sin\theta + \mu cos\theta)

now plug in all values in it

a = -9.81(sin20 + 0.2cos20)

a = -5.2 m/s^2

now the distance covered by the puck along the plane is given as

v_f^2 - v_i^2 = 2 a d

0 - 10^2 = 2(-5.2)d

d = 9.62 m

An automatic dryer spins wet clothes at an angular speed of 4.1 rad/s. Starting from rest, the dryer reaches its operating speed
AleksandrR [38]

Answer:

The time taken by dryer to come up to speed of 4.1 rad/s is 0.95 s .

Explanation:

Given :

Initial angular speed , \omega_i=0\ rad/s .

Angular acceleration , \alpha=4.3\ rad/s^2 .

We need to find how much time it takes to reach a speed of 4.1 rad/s .

Therefore , applying equation of motion .

\omega_f-\omega_i=\alpha\times t\\\\4.1-0=4.3\times t\\\\t=\dfrac{4.1}{4.3}\ s\\\\t=0.95\ s

The time taken by dryer to come up to speed of 4.1 rad/s is 0.95 s .
