What is the change in velocity of a 22-kg object that experiences a force of 15 N for
vagabundo [1.1K]

Answer:

Force = mass × acceleration

Acceleration:

{ \tt{15 = (22 \times a)}} \\ { \tt{a =  \frac{15}{22}  \:  {ms}^{ - 2} }}

From first Newton's equation of motion:

{ \bf{v = u + at}}

Change = v - u:

{ \tt{v - u = (a \times t)}} \\ { \tt{v - u = ( \frac{15}{22} \times 1.2) }} \\ { \tt{v - u = 0.82 \:  {ms}^{ - 2} }}

A car is traveling at an initial velocity of 25 m/s slows to a stop in 10 seconds. What is the acceleration of the car?
Rufina [12.5K]

Answer:

2.5 m/s^2

Explanation:

the formula for acceleration (or the one you use in this case) is a=vf-vi/t

where vf is equal to final velocity, vi is equal to initial velocity, and t is equal to time.

vf= 25 m/s

vi= 0m/s

t=10s       25-0=25, 25/10=2.5 therefore it is 2.5m/s^2

Which principle states that sediments are deposited in sequence unless they are disturbed
Volgvan

The manner in which the sediments are being deposited unless the disturbance by tectonic processes makes it non sequential is theorized with the principle of superposition.

<u>Explanation: </u>

The principle of superposition lets us know that the oldest sediment layer is at the bottom with the newer at the top. For example, xenolith in igneous rock must be older than the rock it contains.

The formation of sedimentary rocks is done via sedimentation occurring in the sequential basis. Due to tectonic process or disruption or even say faults, the layers are sediment in non sequential manner. The entire manner of sequential layering gets turn upside down.
