Answer:
Speed is 34.5 m/s
Explanation:
From the third equation of motion:
[tex]{ \boxed{ \sf{v {}^{2} = {u}^{2} + 2as}}}[/tex]
v is final velocity, u is initial velocity, a is acceleration, s is displacement.
substitute:
[tex] {v}^{2} = {30}^{2} + (2 \times 2.4 \times 60) \\ {v}^{2} = 900 + 288 \\ {v} {}^{2} = 1188 \\ {v} = \sqrt{1188} \\ v = 34.5 \: m {s}^{ - 1} [/tex]
