"Malaysia Prime Minister Mahathir Mohamad and the Sultan of Johor are seen in a blue Proton Saga... "When asked whether there is any tension with the sultan, Dr Mahathir said: “No, I don’t see anything because I went to see him and he drove me to the airport.

A Physics exam question:


"Ah beng was illegally racing on lim chu kang road last night, and his souped-up GTI can reach a speed of 100 km/h in 3 secs. Calculate the acceleration of the car

His car has a mass of 1.5 tonnes, and his boot contains weapons weighing 100 kg. Ah Beng and his lian gf weighs 160 kg (unborn child included). Calculate the average force developed by the car engine.

In an attempt to escape from the TP, he makes a sharp turn into the cemetery, following a circular path of radius 4 m and at a speed of 15 m/s. Calculate the centripetal force required to keep the car from skidding.

However he fails to complete the turn and slides out, and the car collided with a tombstone, causing the air bag to be deployed. Ah Beng and lian girlfriend walked out alive.

Discuss how the use of airbags in his GTI saved 2 (3) lives.

There u have it, a 10mark structured qn"
