A motorboat starting from rest on a lake acceleration line at a constant rate of `3.0 m//s^(2)` for `8.0 s`. How far does the boat travel during this time ? |
|
Answer» Here, `" "` Distance travelled, s = ? `" "` (To be calculated) `" "` Initial speed, `u` = 0 `" "` Time, `t` = 8.0 s And `" "` Acceleration, `a` = 3.0 m `s^(-2)` Now, `" "s=ut + (1)/(2) at^(2)` So, `" "s= 0xx8.0 + (1)/(2)xx3xx(8.0)^(2)` `" "s = 0+(1)/(2)xx3xx64` `" "s` = 96 m Thus, the boat travels a distance of 96 metres. |
