Question

a body travels from a distance of 15 m from A to B and then moves a distance of 20 m at right angles to AB. calculate the total distance travelled and displacement

Answer 1

total distance =15+20=30m and displacement =25m

Answer 2

Solution:-

given by:-

》distance A TO B = 15 M

》B to C = 20 m

》total distance = 35m

》displacement = AC^2 = AB^2 + BC^2

》 = AC = (15^2+20^2)^1/2

》 = AC = ( 225+400)^1/2

》 = AC = 625^1/2

》 =( AC = 25 m)ans
