distance covered: 10+4 = 14 km
speed = distance/time = 14km/2hr = 14/2 = 7 km/hr
displacement = √10^2+4^2) = √116 ≈ 10.77 km
in the direction θ where tanθ = 4/10
so velocity = 10.77/2 = 5.38 km/hr in the direction E21.8°N
A car moves 10km to East and 4km to North,if it takes 2hours calculate the speed and velocity
