#82

here we know that

acceleration = 2 m/s/s

time = 5 s

initial speed = 4 m/s

now we can use kinematics to find the final speed

$v_f = v_i + at$

$v_f = 4 + 2(5)$

$v_f = 14 m/s$

So correct answer will be option D)

#83

here we know that

acceleration = 3 m/s/s

time = 4 s

initial speed = 5 m/s

now we can use kinematics to find the final speed

$v_f = v_i + at$

$v_f = 5 + 3(4)$

$v_f = 17 m/s$

So correct answer will be option C)

#84

here we know that

acceleration = 7 m/s/s

time = 3 s

initial speed = 8 m/s

now we can use kinematics to find the final speed

$v_f = v_i + at$

$v_f = 8 + 7(3)$

$v_f = 29 m/s$

So correct answer will be option C)

A truck moving at 20 mph shoots a soccer ball at 20 mph in the opposite direction. How fast is the soccer ball moving? Explain

Brrunno [24]

Answer:

Speed of the soccer ball with respect to ground is ZERO

Explanation:

As we know that truck is moving with speed 20 mph

Now a soccer ball is shoot from truck with respect to the motion of truck in opposite direction

The relative speed of the soccer ball is

$v_{bt} = 20 mph$

now we know that

$v_{bt} = v_b - v_t$

so we have

$-20 mph = v_b - 20$

so we have

$v_b = 0$

Briefly explain why small-angle grain boundaries are not as effective in interfering with the slip process as are high-angle gra

artcher [175]

Answer:

Compared to High angle, relatively less presence of Crystallographic misalignment in grain boundary for small angle is reason behind its less effectiveness in interfering with slip process

Explanation:

Because of relatively much less presence of crystallographic misalignment in grain boundary for small angle, small grain boundaries are not as effective in compare to high angle in interfering with slip process

Less crystallographic misalignment in grain boundary causes not much change in slip direction and therefore interference to slip process is minimal.
