Linear Motion Physics

A cyclist travelling at a speed of 4.2 m s^-1 accelerates at 1.1 m s^-2. In a time of 7.4 s, the distance travelled is

• 30 m

• 35 m

• 61 m

• 91 m

A bus is travelling at a speed of 9.0 m s^-1. It then accelerates at a rate of 0.75 m s^-2 for a time of 8.0 s. What therefore is its final speed?

• 6.0 m s^-1

• 15 m s^-1

• 17 m s^-1

• 21 m s^-1

Velocity is ...

• Same as force

• Same acceleration

• speed with a direction

• same as force

How do you calculate distance?

• Distance divided by time.

• Displacement divided by time.

• Speed multiplied by time.

• Displacement divided by velocity.

The distance traveled by an object per unit time is called

• acceleration

• gravity

• force

• speed
