Answer 1

Answer:

Speed is the distance covered by a body in unit time whereas velocity is the displacement covered.

Speed is scalar and velocity is vector.

Speed cannot be zero or negative, but velocity can be.

2) Odometer measures the distance covered by a vehicle.

3)50km/h can be converted to m/s by multiplying by 5/18 = 250/18= 13.8 m/s

4)Distance will be 2400-2000 = 400km

time = 8h

Average speed = 400/8 = 50km/h or 13.8m/s

5)u = 80km/h

v= 60km/h

t= 5s

a= v-u/t = 20*5/18 /5 = 20/18= 1.1m/s^2

Hope it helps you
