Answer:

Car B

Explanation:

Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.

According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.

The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.

A snowboarder starts from rest on an inclined planar snow surface and gives herself a tiny push to start sliding down the hill.

tiny-mole [99]

Answer:

v = 26.52 m/s

Explanation:

Here we know that as she passes the flag she will gain some speed

so here we can say that

Work done by all forces = change in kinetic energy of the system

so we will have

$W_g + W_f = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2$

here we know that

$W_g = mgh$

$W_f = -\mu mg d$

$v_i = 0$

h = 39.78 m

d = 27.81 m

so we have

$mgh - \mu mg d = \frac{1}{2}mv^2 - 0$

$(9.8)(39.78 - (0.14)(27.81)) = \frac{1}{2} v^2$

$v = 26.52 m/s$
