Answer» Explanation: Answer: Given :- Initial velocity of bus (U) = 0 m/s Acceleration of bus (A) = 2 m/s Time taken (T) = 4 m ➡ 240 second To find :- ❶ Speed required ❷ Distance travelled SoluTion For find speed, We will use newton first Equation \fbox {v \: = u + at} v = u + at
Here, V = FINAL Velocity U = Initial velocity A = Acceleration T = Time \SF \: v \: = 0 + 2 \times 20v=0+2×20 \sf \: v \: = 0 + 40v=0+40 \sf \: \: v \: = 40 \: mpsv=40mps Now finding distance travelled by using newton third Equation \boxed { \sf \: s \: = UT + \dfrac{1}{2} \times a {t}^{2} } s=ut+ 2 1
×at 2
Here, S = Distance travelled U = Initial velocity T = Time taken A = Acceleration \sf \: s \: = 0 \times 20 + \dfrac{1}{2} \times 2 \times {240}^{2}s=0×20+ 2 1
×2×240 2
\sf \: s \: = 0 + \dfrac{1}{2} \times 240 \times 240s=0+ 2 1
×240×240 \sf \: s \: = 57600 \: ms=57600m |
