A go-kart and its driver have a combined mass of 180 kg180\text{ kg}180 kg.
On a straight horizontal section of a track, the go-kart accelerates from rest at 4.5 m/s24.5\text{ m/s}^24.5 m/s2.
The go-kart reaches the end of the straight section in 6.2 s6.2\text{ s}6.2 s. Calculate the speed of the go-kart at the end of the straight section.
Calculate the magnitude of the resultant force on the go-kart and driver on this straight section.
At the end of the straight section, the track remains horizontal but bends to the left. When the go-kart reaches the bend, it travels around the bend in a circular path at a constant speed.
Velocity is a vector quantity. State how a vector quantity differs from a scalar quantity.
Describe what happens to the velocity of the go-kart as it travels around the bend at a constant speed.
Explain why there must be a resultant force on the go-kart as it travels around the bend.
