A racing car has uniform acceleration of\[\text{4m}/{{\text{s}}^{\text{2}}}\]. What distance will it cover in 10 seconds after the start?

Answer:

Here, Initial velocity, u = 0, (starts from rest) Uniform acceleration,\[a=4\,m{{s}^{-2}}\] Time taken, t = 10s Distance covered S = ? (to be calculate(d) From formula, \[S=ut+\frac{1}{2}a{{t}^{2}}\] Putting values, we get, \[S=0\times t+\frac{1}{2}\times 4\times {{(10)}^{2}}=\frac{1}{2}\times 4\times 100\] \[S=100\,m.\]
