Answer: Acceleration = 1m/s2 and Distance = 144 metres
Explanation: Initial Velocity(u) = 6m/s (Speed at the Beggining)
Final Velocity(v) = 8m/s (Speed at the End)
Time = 12 Seconds
There is a formula to calculate Acceleration... Lets apply that..
Acceleration = Final Velocity - Initial Velocity/Time
In short cut
Acceleration = v-u/time
v= Final Velocity
u= Initial Velocity
Acceleration = 8m/s - 6m/s/12
Acceleration = 2m/s divided by 2
2 divided by 2 = 1.. Soo,
Acceleration = 1m/s2
Lets Calculate Distance now...
There is a formula for that too...
Distance(s)= (u x t) + a x t x t/2
Distance(s)= (6 x 12) + 1 x 12 x 12/2
Distance(s)= 72 + 144/2
Distance(s)= 72 + 72
Distance(s)= 144 Metres
