What is pressure in physics

1 answer:

8 0

Pressure is the force per unit area. This means that the pressure a solid object exerts on another solid surface is its weight in newton’s divided by its area in square metres

A 50.0-kg skater begins a spin with an angular speed of 4.0 rad/s. By changing the position of her arms, the skater decreases he

Pani-rosa [81]

Answer:

The Skater's final angular speed =8rad/s

Explanation:

Let initial momentum of inertia be I1

Let final momentum of inertia be I2

But I2= I1/2

It is decreased by one-half

There is no external torque on the system, therefore

I1w1=I2w2

I1×4=(I1/2)×w2

Dividing through by I1 on both sides leaves you with:

4=w2/2

Cross multiply

W2=4×2=8rad/s

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

$v_f^2 - v_i^2 = 2 a d$

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

$d = 9.62 m$
