Answer:
5 m/s²
Explanation:
From the questio,
Acceleration (a) = Change in velocity(Δv)/time(t)
a = Δv/t
a = (v-u)/t.................. Equation 1
Where v = final velocity, u = initial velocity, t = time
Given: v = 15 m/s, u = 5 m/s, t = 2 seconds
substitute these value into equation 1
a = (15-5)/2
a = 10/2
a = 5 m/s².
Hence her accleration is 5 m/s²
