The Gond are also known as the Raj Gond. The term was widely used in 1950s, but has now become almost obsolete, probably because of the political eclipse of the Gond Rajas.[5][page needed] The Gondi language is closely related to the Telugu, belonging to the Dravidian family of languages. About half of Gonds speak Gondi languages while the rest speak Indo-Aryan languages including Hindi.[citation needed]
According to the 1971 census, their population was 5.01 million. By the 1991 census this had increased to 9.3 million[5][page needed] and by 2001 census this was nearly 11 million. For the past few decades they have been witnesses to the Naxalite–Maoist insurgency in the central part of India.[6] Gondi people, at the behest of the Chattisgarh government, formed the Salwa Judum, an armed militant group to fight the Naxalite insurgency.

GIVEN
Initial velocity(u) = 0 m/s
Acceleration (a) = 10 m/s²
Time(s) = 20 m
We know,
v² = u² + 2as
Putting values:
v² = 0² + 2 (10 x 20)
v² = 400
v = 20 m/s
For time:
v = u + at
t = v - u/a
t = (20-0)10
= 20/10
= 2
∴ Striking velocity = 20 m/s
∴ Striking Time = 2 seconds
