A car of mass 1500 kg is travelling at a speed of 20m/s. Calculate its kinetic energy

Answers

Given,

Mass, m=1500kg

Velocity, v=20m/s

KE= 1/2mv^2

KE=1/2 x 1,500 x 20^2

KE=300000 J

KE=300 kJ

You travel in a circle, whose circumference is 8 kilometers, at an average speed of 8 kilometers/hour. If you stop at the same point you started from, what is your average velocity?

Answers

Answer: The average velocity will be 0 m/s.

Explanation:

Average velocity is defined as the fraction of displacement and total time.

$\text{Average velocity}=\frac{Displacement}{\text{total time}}$

In the given question, it states that the person stops at the same point from where it started, which means that the displacement of this person is 0 meters.

Therefore, the average velocity becomes:

$\text{Average velocity}=\frac{0}{\text{total time}}=0m/s$

Hence, the average velocity will be 0 m/s.

the answer is 8 kilometers per hour

A worker pulls horizontally on a crate across a rough horizontal surface, causing it to move forward with constant velocity. Force A is the force exerted by the worker and force B is the force of friction due to the surface. What is the relationship between A and B?A > B
A = B
A< B
It will not slow down, but continue moving at constant velocity.

Answers

Answer:

$A = B$

Explanation:

A work pulls the crate by horizontal force on it

Now due to this applied force crate is moving horizontally with uniform speed

so we can say that the acceleration of the crate will be zero

now by Newton's II law we can say

$F_(net) = 0$

$F - F_f = 0$

so here we will have

$F_f = F$

here we know that applied force is A

so F = A

and friction force is B

$F_f = B$

so correct relation is

$A = B$

If an object is moving at a constant velocity ( That means a constant speed in a straight line. ) the net force acting on the object is zero, nothing. Why? It's motion is described by Newton's first law: An object at rest will remain at rest and an object in motion will remain in motion moving at constant velocity unless acted by an outside force.
