You are woken up in the morning on the farm by a rooster. The rooster is located 30 meters away on top of the 5 meter barn house

Complete Question

The complete question is shown on the first uploaded image

Answer:

The velocity is $v = 18.73 \ m/s$

Explanation:

From the question we are told that

The distance of the rooster from farm house is $d = 30 \ m$

The height of the rooster from the ground is $h = 5 \ m$

The angle at which the alarm clock is thrown is $\theta = 53 ^o$

Let the velocity at which the alarm clock is thrown be v

So the horizontal component of v is mathematically represented as

$v_h = v cos \theta$

The distance covered by the alarm clock toward the horizontal direction at velocity v is

$d = v_h$

=> $d = v_h = vcos \theta * t$

=> $vcos \theta * t = 30$

substituting for $\theta$

$v (cos (53)) * t = 30$

=> $v * t = 50$

Considering the motion of the alarm clock in the vertical direction

So the vertical component of v is mathematically represented as

$v_v = vsin \theta$

The distance covered in the vertical direction is mathematically evaluated as follows

From the equation of motion we have

$h = vsin\theta * t - \frac{1}{2} g t^2$

$v* t sin\theta - 4.9t^2 = 5$

Recall $v * t = 50$

$50 \ sin \theta -4.9t^2 = 5$

substituting for $\theta$

$50 \ sin (53) -4.9t^2 = 5$

=> $t =\sqrt{7.1289}$

$t =2.673 \ s$

Now

$v * t = 50$

$v * 2.673 = 50$

=> $v = 18.73 \ m/s$

The 20 g bullet is traveling at 400 m/s when it becomes embedded in the 2 -kg stationary block. Determine the distance the block

Marina CMI [18]

Answer:

The block+bullet system moves 4 m before being stopped by the frictional force.

Explanation:

Using the law of conservation of llinear momentum and the work energy theorem, we can obtain this.

According to Newton's second law of motion

Momentum before collision = Momentum after collision

Momentum before collision = (0.02×400) + 0 (stationary block)

Momentum before collision = 8 kgm/s

Momentum after collision = (2+0.02)v

8 = 2.02v

v = 3.96 m/s.

According to the work-energy theorem,

The kinetic energy of the block+bullet system = work done by Friction to stop the motion of the block+bullet system

Kinetic energy = (1/2)(2.02)(3.96²) = 15.84 J

Work done by the frictional force = F × (distance moved by the force)

F = μmg = 0.2(2.02)(9.8) = 3.96 N

3.96d = 15.84

d = (15.84/3.96) = 4 m
