Answer:

120 J

Explanation:

KE = 1/2 mv²

KE = 1/2 (0.15)(40)²

KE = 1/2 (0.15)(1600)

KE = 1/2 (240)

KE = 120 J

During a race, a runner runs at a speed of 6 m/s. Four seconds later, she is running at a speed of 14 m/s. What is the runner's
DedPeter [7]

Answer:

D. 2 m/s²

Step-by-step explanation:

Initial speed of the runner (u) = 6 m/s

Final speed of the runner (v) = 14 m/s

Time taken (t) = 4 s

By using equation of motion, we get:

\bf \longrightarrow v = u + at \\  \\  \rm \longrightarrow 14 = 6 + 4a \\  \\  \rm \longrightarrow 14 - 6 = 6 - 6 + 4a \\  \\  \rm \longrightarrow 8 = 4a \\  \\  \rm \longrightarrow 4a = 8 \\  \\  \rm \longrightarrow  \dfrac{4a}{4}  =  \dfrac{8}{4}  \\  \\  \rm \longrightarrow a = 2 \: m {s}^{ - 2}

\therefore Acceleration of the runner (a) = 2 m/s²
