Motion in One Dimension

If two speedboats pass each other going opposite directions and each are moving 10 km/hour, they have the same-

• distance

• velocity

• length

• speed

Distance travelled by the body in 5 minutes if it travels with a speed of 20 ms^-1.

• 6 m

• 60000 m

• 6 km

• 45 km

A car moving on a straight line path covers a distance of 2 km due east in 100 s, the speed & velocity of the car is

• 20 ms^-1 and 20 ms^-1

• 20 ms^-1 and 40 ms^-1

• 20 ms^-1 and 20 ms^-1 due south

• 20 ms^-1 and 20 ms^-1 due east

A cycle initially moving with a velocity of 5 ms^-1 accelerates for 5 s at a rate of 2 ms^-2 , final velocity will be

• 10 ms^-1

• 100 ms^-1

• 35 ms^-1

• 15 ms^-1
