Question
The motion of a body is given by the equation 
Where 
at time t is in ms–1 and t is in seconds. If the body was at rest at t = 0, test the correctness of the following results are. The terminal speed is
- 2 ms–1
- 2 ms–2
- 3 ms–1
- 2 ms
The correct answer is: 2 ms–1
The terminal speed is the speed when the acceleration is zero. Setting a(t) = 0 in Eq.(i), we have 0 = 6 – 3n orterminal speed (n) = 6/3 = 2 ms–1
