See below.

The following are the guidelines for creating ray diagrams for the generation of an image by a concave mirror:

Rule 1: If the incident ray is parallel to the major axis, the reflected ray will pass through the concave mirror's focus.

The reflected ray is parallel to the principal axis if the incident ray passes through the focus of the concave mirror.

Rule 3: If the incident ray passes through the concave mirror's center of curvature, the reflected ray follows the same path.

Hope this helps!

Kelly is riding a bicycle, moves with an initial velocity of 5 m/s. Ten seconds later, she is moving at 15 m/s. What is her acce

sladkih [1.3K]

Answer:

her acceleration is 1 m/sec

Explanation:

The following information is given in the question

The initial velocity is 5 m/s

After 10 seconds, she would be moved at 15 m/s

We need to find the acceleration

As we know that

Acceleration = Change in speed ÷ time

Acceleration = (15 - 5) ÷ (10)

= 1 m/sec

Hence, her acceleration is 1 m/sec

A 5000kg car traveling at 40m/s crashes into a wall and comes to a complete stop in 10s. What was the force on the wall? solve s

IrinaK [193]

Answer:

20,000 N

Explanation:

First find the acceleration:

a = Δv / Δt

a = (0 − 40 m/s) / 10 s

a = -4 m/s²

Next use Newton's second law to find the force on the car:

F = ma

F = (5000 kg) (-4 m/s²)

F = -20,000 N

According to Newton's third law, the force on the wall is equal and opposite the force on the car.

F = 20,000 N

A speed skater is sliding across the ice at a speed of 19 m/s when she encounters a rough patch of ice that is 2.0 m wide. As sh

Stells [14]

Answer:

$-9.25 m/s^2$

Explanation:

The motion of the skater is a uniformly accelerated motion, so we can find the deceleration by using the following suvat equation:

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

In this problem, we have:

u = 19 m/s is the initial velocity of the skater

v = 18 m/s is the final velocity of the skater

s = 2.0 m is the displacement

Solving for a, we can find the acceleration:

$a=\frac{v^2-u^2}{2s}=\frac{18^2-19^2}{2(2.0)}=-9.25 m/s^2$

And the negative sign tells us that the acceleration is in the opposite direction to the motion (so, it is a deceleration)
