Question

24. A car starts from rest and accelerates at 2 m/s2 for
5 seconds, then travels at a steady speed for
another 5 seconds, in same direction. The distance
it has covered for entire 10 seconds is
(1) 50 m
(2) 25m
(3) 40 m
(4) 76m

Answer 1

Answer:

s= ut+1/2at^2

s= 0×5+ 1/2 ×2× 25

= 25m

v=s/t

s= vt

= 10×5

= 50
