1) Derive the equation of motion v 2 – u2 = 2as graphically. 2) Derive the equation of motion s = ut + ½ at2 graphically.

3) A racing car has a uniform acceleration of 5m/s2 . what distance will it cover in 20s after the start?

4) A body undergoes an acceleration of 10m/s2 starting from rest. Find the distance travelled by it in 5s?

5) A ball is gently dropped from a height of 20m. if its velocity increases uniformly at the rate of 10m/s2 , with what velocity will it strike the ground? After what time will it strike the ground?

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
