compare the time taken by the RC car to cover the same distance. Do some go faster or slower?

Respuesta :

There isn;t enough given values to define and determine what is asked. But since
distance = speed / time, time = distance / speed


Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario. 


Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds   

Solution: 
A = 45 m/s – 15m/s / 6s 
A = 5m/s^2

The shorter the time required to cover the same distance, the greater the speed of the RC car.

Further explanation

Acceleration is rate of change of velocity.

[tex]\large {\boxed {a = \frac{v - u}{t} } }[/tex]

[tex]\large {\boxed {d = \frac{v + u}{2}~t } }[/tex]

a = acceleration (m / s²)v = final velocity (m / s)

u = initial velocity (m / s)

t = time taken (s)

d = distance (m)

Let us now tackle the problem!

The formula for finding speed is:

[tex]\large {\boxed {v = \frac{s}{t}} }[/tex]

v = velocity (m/s)

s = distance (m)

t = time taken (s)

From the formula above, it is clear that speed is inversely proportional to travel time. The shorter the time required to cover the same distance, the greater the speed of the RC car.

For example, let's look at the data in the table in the attachment. RC Car B has the greatest speed
