Question

1. A driver is speeding along at 120 km/hour when he sees a cat crossing the road approximately 200 meters in front of him. Suddenly he applied the brake, but it took 12 seconds to come to a complete stop. a. What was the acceleration of the car after the break? -2.7 b. Does the cat survive? Yes c. How fast was the car moving when it was 100 meters away from the man? 2. A car moving in a straight road with a constant acceleration. It changes its velocity from 10 ms?¹ to 20 ms?¹ while passing through a distance 135m. Find the time taken to reach the final velocity? 3. Researchers conducted two experiments on a newly discovered planet to find the gravitational acceleration. First, a 2 kg mass is thrown downward from a height at initial velocity 55 km/hr, reaching the surface in 1 second. In the second, the same mass is dropped from rest the same height and takes 2 seconds. Determine the planet's gravitational acceleration?
