1.Gino, an experienced driver, was asked to test-drive the new Ferrari F40 sports car. This car has a distinction of having the world’s fastest acceleration, which was measured at 6.74 m/s². Starting at rest, the suddenly pressed his right foot on the accelerator. After 4 seconds, what is the velocity of Gino’s car in km/h? 2.Starting at rest, a rocket moves vertically upward with an acceleration of 30 m/ s². After 4 seconds, it runs out of fuel and continues to moves upward under the influence of gravity. How high can the rocket rise? 3.You are driving your car at a constant velocity of 50 km/h when you spot an intersection 250m away prompting you to step on the brakes. How fast should your car constantly decelerate in km/h so as to come to full stop just before the intersection? thanks.
