If the velocity of a car moving with uniform velocity changes from 20m/s to 40m/s in 5s
What is the acceleration of the car?

If the velocity of a car moving with uniform velocity changes from 20m/s to 40m/s in 5s What is the displacement by the car during this time interval?

A car starts from rest and covers 25m in 5s. Calculäte the acceleration of the car.

"The graphical method of adding vectors helps us in visualizing the vectors and the resultant vector.But, sometimes, it is tedious and has limited accuracy." a)Name the alternative method of vector addition. b)Write a mathematical expression to find resultant of two vectors. c)A particle is moving eastward with a velocity of 5m/s .If in 10s ,the velocity changes by 5m/s northwards,what is the average acceleration in this time.

If a velocity of a train which starts from rest is 72km/h (20m/s) after 5 minute, find out its acceleration and the distance travelled by the train in this time.

A loaded lorry of mass 12000kg moves with a velocity of 12m/s. its velocity becomes 10m/s after 5s what is the rate of change of momentum?

A constant force is applied for 2 s on a body of mass 5kg. As a result, if the velocity of the body is changed from 3m/s to 7m/s, find out the value of the applied force.

A car of 1000kg moves with a velocity 20m//s . On applying brakes it comes to rest in 5s. What is the final momentum?

The velocity of a body starting from rest is 20m/s in the 4th second and 40m/s in the 8th second. What is the distance travelled by the body between the 4th and 8th second?
