Question

A car moves with speed 60km/h for 1hour in East direction and with same speed for 30 minutes in South direction the displacement is

Answer 1

Solution :

⏭ Given:

✏ A car moves with speed 60kmph for 1h in east direction and with same speed for 1/2 h in south direction

⏭ To Find:

✏ Displacement of car

⏭ Concept:

✏ Displacement is defined as the shortest distance between the two points.

⏭ Formula:

✏ We know the basic formula of Distance that,

• Distance = speed × time

⏭ Calculation:

• Distance covered in east

✏ d1 = 60 × 1

✏ d1 = 60km

• Distance covered in south

✏ d2 = 60 × 1/2

✏ d2 = 30km

• Displacement

✏ Please, see the attachment for calculation of displacement

✏ Displacement = 67.08 km

⏭ Additional information:

• Displacement is vector quantity.
• Distance travelled is scalar quantity.
• Displacement can be positive, negative and zero.
