Question

40) A body starts from rest and moves with a uniform acceleration of 4 m/s2. Calculate the
displacement of the body in 10 seconds.
​

Answer 1

Answer:

displacement =ut +1/2at^2

0+1/2×4×10^2

=2×100

=200m

Answer 2

Answer: 200m

Given:

u= 0 m/s

a= 4 m/s^2

t= 10 sec

To find: Displacement (s)

Solution:

s = ut + 1/2at^2

s = 0×10 + 1/2×4×10^2

s = 2×100

s = 200m

Hence, displacement after 10 seconds is 200m.
