Why is it easier to start a car engine on a warm day than on a chilly day ?

Draw the graphs for the following tables of values, with suitable scales on the axes. Distance travelled by a car What was the time when the car had covered a distance of 100 km since it's start?

Work Problem related to speed, distance and time Places A and B are 70km apart on a highway. A car starts from A and another car start from B at the same time. If they travel in the same direction they meet in seven hours but if they travel towards each other meet in one hour. What are their speed.

Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method:Places A and B are 100km apart on a highway.One car starts from A and another from B at the same time.If the car travel in the direction at different speeds,they meet in 5 hours.If they travel towared each other,they meet in 1 hour .What are the speeds of the two cars?

Work Problem related to speed, distance and time Two places A and B are at distance 160km . Two cars starting form tha same place and moving in the same direction meet after eight hours. Again moving in the oppoosite directions from A to B. The cars meet each other after one hour. Find the speed of the cars.

A car and a bus start from a place P at the same time and move non-stop towards a place where the distance between P and Q is 210 km. The car takes half an hour less than the bus to arrive Q. If the average speed of the car is 10 km/h more than that of the bus, find the average speed of the car and the bus.

Prove the result that the velocity v of translation of a rolling body (like a ring, disc, cylinder or sphere) at the bottom of an inclined plane of a height h is given by v^2=(2gh)/ (i+k^2^l R^3 Using dynamical consideration (i.e. by consideration of forces and torques). Note k is the radius of gyration of the body about its symmetry axis, and R is the radius of the body. The body starts from rest at the top of the plane.
