Answer:
The acceleration acting on the train during this
time of travel is 0.85m/s²
HOW TO CALCULATE ACCELERATION:
• The acceleration of a moving body can be calculated by using the formula below:
a = (v - u)/t
Where;
1. a = acceleration (m/s²)
2. v = final velocity (m/s) 3. u = initial velocity (m/s)
4. t = time (s)
According to this question, a = ?, v = 48m/s, u = 14m/s, t = 40s.
= (48 - 14)/40 a=
• a = 34/40
• a = 0.85m/s²
Therefore, the acceleration acting on the train during this time of travel is 0.85m/s².
