Question

A bike travel a distance of 500m in 30second south ward.
What is the speed of bike.
What is the velocity of bike

Answer 1

Answer:

Speed : 500/30 = 16.67 m/s

Velocity : 16.67 m/s in southward direction.

Answer 2

Given:

• A bike travel a distance of 500m in 30second south ward.

To find:

• The speed and velocity of the bike.

Solution:

$\sf \maltese \: \: \underline {Speed \: of \: the \: bike}$

e know that,

$\sf{Speed=\frac{Distance}{Time}}$

★ Putting values in the formula

$\sf{ \rightsquigarrow \: {S = \frac{500}{30} = 16.6 \: m/s }}$

___________________________________________

$\sf\maltese \: \: \underline{Velocity \: of \: the \: bike}$

We know that,

v=u+at ( From first equation of motion)

Here,

v is velocity

u is initial velocity

a is acceleration

t is time

★ Putting values in the formula

» v = 0 + 9.8(30)

» v = 294m/s

___________________________________________

Therefore,

Speed of the bike = 16.6m/s

Velocity of the bike = 294m/s

✩ Additional information:

• First Equation of Motion » v=u+at

• Second Equation of Motion » s=ut+1/2at^2

• Third Equation of Motion » v^2=u^2+2as
