Answer:
26m/s
Step-by-step explanation:
Acceleration is the change in velocity of a body with respect to time. Mathematically,
Acceleration = change in velocity/time
Acceleration = final velocity (v) - initial velocity (u)/time (t)
Given a = 4m/s², v = ? u = 18m/s, t = 2seconds.
Substituting in the given formula,
4 = v-18/2
8 = v-18
v = 8+18
v = 26m/s
The new velocity of the body is therefore 26m/s
