Find the acceleration of a car that starts at rest and speeds up to 20m/s in 6 seconds moving East.

A. 2.5 m/s²
B. 2.28 m/s²
C. 3.33 m/s²


Sagot :

Answer:

Clculate the acceleration:

V = u +at

20m/s = 0 + a*10s

a = 20m//10s

a = 2m/s²

From the data given , it is not possible to calculate the displacement , because no direction of motion is given

But it is possible to calculate the distance travelled

Distance = ut + ½ *a*t²

distance = 0 + ½ * 2m/s * 10²s

distance = 100m
