CBSE Class 9 Physics Motion
 Two points A and B are located on the floor of a room 30cm and 20cm away from a wall. The distance between the points parallel to the wall is 50cm. An insect is at moving on the floor at 5cm/s. It has to first reach a point C on the wall and then reach B such that AC and BC make equal angles with Normal to the wall at C. The time taken for this motion will be
 A student starts with a velocity 40 km/hr for school at 4 km away from his house. Due to closing of school he returns soon to his house with a velocity of 60km/hr.His average velocity will be.
 a body goes from a to b with a velocity of 20ms and come back from b to a the average velocity of 30ms the average velocity of the body during the whole journey is
 what is vector quantities
 ar Covers 50km in 15 mins and then covers 65km in next 15 mins. calculate it's average speed
 a car is moving with the acceleration 2m/s from rest find the distance traveled by the car in 10th second
 A car travells 33 km south 13 km west and 14 km north in half an hour calculate the average velocity
 briefly explain different type of motions
 in 12 minute a car whose speed is 35km/hr travel with a distance of

Abdul, while driving to school, computes the average speed for his trip to be 20 km/h. On his return trip along the same route, there is less traffic and the average speed is 30 km/h. What is the average speed of Abdul's trip?
