Compare and contrast speed and velocity

1 answer:

8 0

Where speed is distance/time, velocity is displacement/time.

What this means is that velocity is the length covered in relation to the starting point.
Speed is just the distance travelled no matter where you began.

When going around a circular track, you might have a speed value. However, since you get back to the same location at every lap, you have 0 velocity.

Hope I helped :)

SVETLANKA909090 [29]

Answer:

Explanation:

An object's resistance depends on its form and the substance it is made from. The electrical resistance R of the cylinder, as you might expect, is directly proportional to its length L, similar to a pipe's resistance to fluid flow. The longer the cylinder, the more charges of collisions with its atoms can occur. The bigger the cylinder diameter, the more current it can carry.

A car is moving at constant velocity +48.8 m/s along a straight highway. Suddenly the driver spots a stalled vehicle 378.7 m ahe

Katen [24]

Answer:

a = - 3.14[m/s^2]

Explanation:

To solve this problem we must use the following kinematic equation:

$v_{f} ^{2}= v_{o} ^{2}+2*a*dx\\where:\\v_{f} = final velocity = 0 [m/s]\\v_{o}= initial velocity = 48.8 [m/s]\\ a = acceleration [m/s^2]\\dx = displacement [m]\\$

Now replacing:

$0 = 48.8^{2}+2*a*(378.7) \\-2381.44 = 757.4*a\\a = -3.14[m/s^2]$

The negative sign means the vehicle slows down.

Suppose the roller-coaster car in fig.6–41 passes point 1 with a speed of if the average force of friction is equal to 0.23 of i

madreJ [45]

The values in figure 1 shows h1 = 39 m, h2 = 13 m, h3 = 25 with a speed of 1.5m/s

The Initial speed u = 1.5m/s.

Vertical distance covered between point 1 and point 2 is (39-13) =26m

The expanse 45 m is equal to a height of (45/6) =7.5 (As frictional force is mg/6)

With the kinematics equation v^2 =u^2 + 2as

V^2 = 1.5^2 + 2*9.8 (26 + 7.5)

V = 25.7 m/s
