The world's fastest production sportscar has a top speed of 415 kmh-1(a)Convert this speed to ms-1.[ 1](b)The distance from London to Edinburgh is 403 miles. There are 1609 metres in a mile. How long would it take the car to travel from London to Edinburgh if it was able to travel at top speed? Give your answer to the nearest minute.[ 4](c)The International Space Station travels at 7.66 km s-1. In the time it takes the car to travel from London to Edinburgh, how far will the International Space Station have travelled?[ 2](d)Speed and velocity have different definitions in physics –yet both are measured in ms-1. Explain the difference

(a). The speed is 115.28 m/s.

(b). The time is 94 min.

(c). The International Space Station travels 43202.400 km.

(d). Speed is scalar quantity.

Velocity is vector quantity.

Explanation:

Given that,

Top speed = 415 km/h

1 miles = 1609 m

(a). We need to calculate the speed in m/s

Using conversion of km/h to m/s

(b). We need to calculate the distance from London to Edinburgh in km

Using conversion for distance

Distance in meter,

We need to calculate the time

Using formula of time

Put the value into the formula

(c). Speed v' =7.66 km/s

v'=7660 m/s

In the time it takes the car to travel from London to Edinburgh,

We need to calculate the distance

Using formula of distance

Put the value into the formula

(d). Speed :

Speed is equal to the distance divided by time.

It is scalar quantity.

Velocity :

Velocity is equal to the displacement divided by time.

It is vector quantity.

Hence, (a). The speed is 115.28 m/s.

(b). The time is 94 min.

(c). The International Space Station travels 43202.400 km.

(d). Speed is scalar quantity.

Velocity is vector quantity.

we need to know the time interval during which the force acts. impulse of force = momentum change

c. magnitude and direction
