A 1000 kg car is rolling slowly across a level surface at 1m/s, heading toward a group of small innocent children.

Ne4ueva [31]

Answer:

The force is -1620.73 N.

Explanation:

Given that,

Mass of car = 1000 kg

Velocity = 1 m/s

Distance = 2 m

Angle = 30°

We need to calculate the force

Using formula of work done

$W_{net}=K_{f}-K_{i}$

$F\times d=K_{f}-K_{i}$

$Fd\cos\theta=-K_{i}$

$F=\dfrac{-K_{f}}{d\cos\theta}$

$F=-\dfrac{\dfrac{1}{2}mv^2}{d\cos\theta}$

Put the value into the formula

$F=-\dfrac{\dfrac{1}{2}\times1000\times(1)^2}{2\times\cos30}$

$F=-1620.73\ N$

Hence, The force is -1620.73 N.

Challenge question: An arrow is placed at 3 centimeters to the left of a converging lens. The image appears at 3 centimeters to

Zanzabum

The focal length of the converging lens based on the arrow placed 3 centimeters to the left and the imaged formed 3 cm to the right is 1.5 cm.

<h3>Focal length of the converging lens</h3>

The focal length of the converging lens is determined by applying the following converging lens formula.

1/f = 1/v + 1/u

where;

v is the image distance = 3 cm
u is the object distance = 3 cm
f is the focal length = ?

1/f = 1/3 + 1/3

1/f = 2/3

f = 3/2

f = 1.5 cm

Thus, the focal length of the converging lens is 1.5 cm.

Firecrackers 1 and 2 are 600 m apart. You are standing exactly halfway between them. Bob is standing 300 m on the other side of

Afina-wow [57]

Answer:

the same time

Explanation:

since the speed of light is very fast (3×10^8 ms^-1) the difference in time arrived from firecrackers A and B to Bob is negligible, and our brain can distinguish such small time difference,l.
