ICSE Class 9 Physics Motion in One Dimension
 If a train moves 25km/sec and decrease to 15km/sec by applying brake in 5 sec then what will be the force of brake
 Laws of motion equations

plz solve urgently dear experts :
 a car moving with a velocity of 72 km h1 is brought to rest by applying brakes in 15 seconds find the retardation of the car
 If car A is travelling at the speed of 80 km/h and car B at 60 km/h in the same direction, what is the velocity of the car A relative to the car B?
 A train is moving with a velocity of 90 km hl. It is brought to stop by applying the brakes which produce a retardation of 05 m s2. Find: (i) the velocity after 10 s, and the time taken by the train to come to rest. Plot on graph
 what is projectile motion
 all equations of motion?
 A train starts from rest and accelerates uniformly at A rate of 2ms1 for 10s.It then maintains A constant speed for 200 s. Tge brakes are then applied and the train is uniformly retarded and comes to rest in 50 s. Find (i) the maximum velocity reached(ii) the retardation in the last 50 s (iii) the total distance travelled, and (iv) the average velocity of the train.

when brakes are applied to a bus, the retardation produced is 25 cm s^2 and the bus takes 20 second to stop calculate the initial velocity of the bus and the distance travelled by bus during this time
