Solution:
To find acceleration:
v2 = u2 +2as
302 = 102 + 2xax4000
900 = 100 + 8000 a
a =
a= m/s2
To find the time taken;
v = u+at
30 = 10 + x t
30-10 =
t/10 = 20
t= 200s
PhysicsA car moving with a velocity of 10m/s and with a uniform acceleration gains a velocity of 30m/s after travelling a distance of 4km then the time taken is:
