Question 1 Report
A train with an initial velocity of 20ms-1 is subjected to a uniform deceleration of 2ms-2. The time required to bring the train to a complete halt is
Answer Details
The time required to bring a train to a complete halt can be calculated using the formula:
Time = velocity / acceleration
where velocity is the initial velocity of the train and acceleration is the deceleration (negative acceleration) experienced by the train.
In this case, the initial velocity is 20 m/s and the deceleration is -2 m/s^2. So, we can calculate the time as follows:
Time = 20 m/s / -2 m/s^2 = 10 s
So, the correct answer is 10 seconds.
