Question
(a) Fig. 1.1. is a speed–time graph for the first 5 minutes of a bus journey.
Describe the motion between:
1. t = 0.90min and t = 2.9min ……………………………………………………………
2. t = 2.9min and t = 3.5min ……………………………………………………………
3. t = 3.5min and t = 4.5min ……………………………………………………………
(b) Another bus travels at a speed of 8.9m/ s. The brakes apply a constant force and the bus stops in a distance of 23m. This bus has a mass of 18000kg.
(i) Calculate the kinetic energy of the bus before the brakes are applied.
kinetic energy = …………………………………………………
(ii) Calculate the force applied to stop the bus.
▶️Answer/Explanation
Ans
(a) constant speed
constant / uniform deceleration
stationary
(b)(i) \(7.1 \times 10^5\) J OR 710 000 J OR 710 kJ
\(EK= \frac{1}{2}mv^2\) OR \((EK= ) \frac{1}{2}mv^2\) OR \(\frac{1}{2} \times 18 000 \times (8.9)^2\)
(ii) 31 000 N OR 31 kN
W = Fd OR (F =) W / d OR 710 000 / 23
F = 710 000 / 23
