Question

A train is accelerating at a rate of 1.8 m/s2. If its initial velocity is 18 m/s,

what is its velocity after 28.1 sec?

Answer 1

velocity= 68.58m/s

Step-by-step explanation:

formula: v = initial velocity + (acceleration)(time)

plug in your values: v= 18m/s + (1.8 m/s2)(28.1s)

solve the parenthesis first: v = 18 m/s + 58.58m/s

add: v = 68.58 m/s
