Answer:

Velocity is a change in displacement over change in time and uses the units m/s.

Both are rates of change and can be positive or negative.

Acceleration is a change in velocity over change in time and uses the units m/s².

Explanation:

Velocity is the change in displacement over change in time, this makes it a rate of change. It can be positive or negative because it is a vector quantity. It uses the units m/s because that is a displacement unit over a time unit.

Acceleration is the change in velocity over change in time, this makes it a rate of change. It can be positive or negative because it is also a vector quantity. It uses the units m/s² (m/s/s) because that is a velocity unit over a time unit.

A 7.5 cm object is 14 cm from a concave lens, which has a focal length of –7 cm. Its image is 5 cm in front of the lens. What is

Rama09 [41]

Given conditions:
height of object = 7.5cmdistance of object from mirror = 14 cmfocus length = -7 cmimage distance = ?
Using mirror formula:
1/(focus length) = 1/(object distance) + 1/(image distance)
or, -1/7 = 1/14 + 1/(image distance)
or, image distance = -4.66cm (the image formed is a virtual image)

Also, magnification of image is:
image height /height of object = - image distance /object distance
or, image height = - image distance / object distance * height of object
or, image height = -(-4.66) / 14 * 7.5 = 2.49 = 3(nearest whole number)

To determine the height of a bridge above the water, a person drops a stone and measures the time it takes for it to hit the wat

myrzilka [38]

The stone will take 2.89 seconds to hit the water.

The time required by the stone to hit the water is calculated by the second equaiton of motion

s=ut+ $\frac{1}{2}$ gt^2

41=0×t+ $\frac{1}{2}$ ×9.81×t²

t=2.89 seconds

An automobile which set the world record for acceleration increase speed from rest to 96 km/h in 3.07 seconds what distance trav

Vesnalui [34]

Answer:

41.02m

Explanation:

Given parameters:

Initial velocity = 0m/s

Final velocity = 96km/hr

Time taken = 3.07s

Unknown:

Distance traveled by the time the final speed was achieved = ?

Solution:

To solve this problem, we first find the acceleration of the car;

Acceleration = $\frac{v - u }{t}$

v is the final velocity

u is the initial velocity

t is the time taken

Now convert the the final velocity to m/s;

96km/hr to m/s;

1 km/hr = 0.278m/s

96km/hr = 96 x 0.278 = 26.7m/s

Now;

Acceleration = $\frac{26.7 - 0}{3.07}$ = 8.69m/s²

So;

v² = u² + 2as

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance

26.7² = 0² + 2 x 8.69 x s

712.89 = 17.38s

s = 41.02m
