CBSE Class 9 - Equations of Motion Videos

• A bus starts from waste moves with the uniform acceleration of 1 m/s² for 5 minutes then what will be the speed acquired and the distance travelled by the bus.
• what is derivation
• A body moving with uniform acceleration  travels 84m in 6seconds and 264m in 11seconds.  Find acceleration and initial velocity? (In detail)
• question 1) A body is projected vertically upwards from top of the tower with the velocity of 30m/s. if it takes 8sec to reach on ground then what is the height of the tower (g=10ms). what is the total distance travelled by the body. question 2) A body is dropped from the height of h covers by 64% distance in its last second.find out thte total tim of the ball and height. question 3) A body projected vertically upward, At the half  of its maximum height its velocity becomes 20m/s, what is the maximum height attained by the body. question 5) A body is projected vertically upward from ground. the time of flight is 8 sec find the velocity of projection.
• can velocity be constant with acceleration?
• A car is traveling with a speed of 54 km/hr the driver applies the break and retards the car uniformly.the car is stopped in 5 seconds 1) The redardation of the car 2)Distance travelled before it is stopped after apply the break
