2.1 Kinematics equations

Question 1

When acceleration is not found / Average speed only

Answer 1

((u + v) / 2) t

Question 2

When distance is not given / Find acceleration

Answer 2

V = u + at

Question 3

Acceleration and Speed are given

Answer 3

S = ut + 1/2 at^2
or
S = vt - 1/2 at^2

Question 4

When time is not given

Answer 4

v^2 = u^2 + 2as
