A car is going at a speed of 21.6 km/hr when it encounters a 12.8 m long slope of angle 30^0 figure. 1/(2sqrt3) . Shwo tht no matter how hard the driver applies the brakes, tehcar will reach the bottim with a speed greater than 36 km/hr. Take g=10 m/s^2

Reaction time : When a situation demands our immediate action, it takes some time before we really respond. Reaction time is the time a person takes to observe, think and act. For example, if a person is driving and suddenly a boy appears on the road, then the time elapsed before he slams the brakes of the car is the reaction time. Reaction time depends on complexity of the situation and on an individual. You can measure your reaction time by a simple experiment. Take a ruler and ask your friend to drop it vertically through the gap between your thumb and forefinger (Fig.). After you catch it, find the distance d travelled by the ruler. In a particular case, d was found to be 21.0 cm. Estimate reaction time.
