A Gipsy car has a canvas top. When the car runs at high speed, the top bulges out. Explain.

In the section 3.7.3 (Banking of road) we have not included the friction exerted by the road on the car. Suppose the coefficient of static friction between the car tyre and the surface of the road is mu_s , calculate the minimum speed with which the car can take safe turn? When the car takes turn in the banked road, the following three forces act on the car. (1) The gravitational force mg acting downwards (2) The normal force N acting perpendicular to the surface of the road (3) The static frictional force f acting on the car along the surface.

A simple pendulum fixed in a car has a time period of 4 seconds when the car is moving uniformly on a horizontal road. When the accelerator is pressed, lthe time period changes to 3.99 seconds. Making an approximate analysis, find the acceleration of the car.

A simple pendulum having bob of mass m is suspended from the ceiling of a car used in a stunt film shooting. The car moves up along an inclined cliff at a speed v and makes a jump to leave the cliff and lands at some the top of the cliff. The tension in the string when the car is in air is

When a person leaves his home for sightseeing by his car, the meter reads 12352 km. When he returns home after two hours the reading is 12416 km. A. What is the average speed of the car during this period? B. What is the average velocity?

A stone dropped from the top of a tower of height 300m splashes into the water of a pond near the base of the tower. When is the splash heard at the top given that the speed of sound in air is 340ms^(-1) ? (g= 9.8ms^(-2))

A ceiling fan has a diameter (of the circle through the outer edges of the three blades) of 120 cm and rpm 1500 at full speed.Consider a particle of mass 1 g sticking at the outer end of a blade. How much force does it experience when the fan runs at full speed? who exerts this force on the particle? How much force does the particle exert on the blade along its surface?
