A car starting from rest and moving on a straight road with 2ms-2 acceleration is observed for 10 seconds. Find 1) The distance travelled by the car in this time. 2) The velocity at the end of this time.

If car is starting from rest then its initial velocity is 0
so u = 0
a = 2
t= 10
2) Using relation v= u+at
v= 0 + 2×10
v = 20 m/s
1) Using relation
v^2 - u^2 = 2as
(20)^2- 0 = 2 × 2 × s
s= 400 / 4
s = 100 m
