The time it will take if a car change the velocity from 36m/s to 28m/s with an acceleration of -2.0m/s² is 4s.

<h3>How to calculate deceleration?</h3>

Deceleration is the amount by which a speed or velocity decreases (and so a scalar quantity or a vector quantity).

The deceleration of a body can be calculated using the following formula:

-a = (v - u)/t

Where;

  • -a = deceleration
  • v = final velocity
  • u = initial velocity
  • t = time in seconds

-2 = (28 - 36)/t

-2t = -8

t = 4s

Therefore, the time it will take if a car change the velocity from 36m/s to 28m/s with an acceleration of -2.0m/s² is 4s.

A girl throws a stone from a bridge. Consider the following ways she might throw the stone. The speed of the stone as it leaves
Len [333]

Answer:

the velocity in all the cases will be same.

Explanation:

given,

girl throws a stone from the bridge

air is friction less

we have to find from the given cases in which case the velocity of stone will be greatest.

According to Work energy theorem work done by the sum of all the force is equal to kinetic energy.

As the air is frictionless hence the speed depend upon the height from which the stone is thrown.

height in all the cases is same.

so, the velocity in all the cases will be same.

Can anyone solve this?
love history [14]

Answer:

F = 39.2 N

Explanation:

Since, the object is in uniform motion. Therefore, the frictional force on object will be:

Frictional Force = μk N = μk mg

where,

μk = coefficient of kinetic friction = 0.2

m = mass of crate = 10 kg

g = 9.8 m/s²

Therefore,

Frictional Force = (0.2)(10 kg)(9.8 m/s²)

Frictional Force = 19.6 N

The horizontal component of force must be equal to this frictional force to continue the uniform motion:

F Sin 30° = 19.6 N

F = 19.6 N/Sin 30°

<u>F = 39.2 N</u>

Johnny walked to the other side of his building using the following steps: 10 meters North, 20 meters to the West, 40 meters Sou
nataly862011 [7]

<u>Answer: </u>

  Distance traveled = 70 meters

  Displacement = 36.06 meters

<u>Explanation: </u>

 Let north be positive Y and east be positive X

 10 meters north, displacement = 10 j meters

 20 meters west, displacement = -20 i meters

 40 meters south, displacement = -40 j meters

 Total displacement = (10 j - 20 i – 40 j) meters = (- 20 i - 30 j) meters

 Magnitude of displacement = \sqrt{20^2+30^2}=\sqrt{1300}= 36.06 meters

 Distance traveled = 10+20+40 = 70 meters
