G9 motion 2

a sprinter runs at a speed of 4m/s find the distance covered in 20 s

• 8 m

• 80 m

• 800 m

a train moves with 80 m/s meet a car move in the same direction with 25 m/s find the relative speed observed by the car driver ................. m/s

• 55

• 105

• 80

a plane moves 1700 km in 2 hours calculate its speed in m/s

• 472.2 m/s

• 118.05 m/s

• 236.1 m/s

a train moves at 10 o'clock in morning what is the time of arrival if it moves at speed of 60 km/hr to cover distance of 600 km then it move with speed 120 km/hr to cover distance of 240 km

• 6 pm

• 8 pm

• 10 pm

what is the average speed in m/s if a car moves 120 km in 2 hr then take rest for 1 hr then move 80 km in 2 hr

• 11.11 m/s

• 22..11 m/s

• 33.33 m/s

find the relative speed if two cars moves in opposite direction .

the first car 120 km/hr and the observer car speed is 60 km/hr

..................... km/hr

• 60

• 120

• 180

....................... is the distance covered in time unit

• speed

• motion
