If S = u t + \frac{1}{2} a t^{2} and u = 50, a = 9.8, t = 2, then the value of S is:

Solution & Step-by-step Explanation

Substitute the given values into the equation of motion: S = u t + \frac{1}{2} a t^{2} Given: u = 50 a = 9.8 t = 2 Calculation: S = (50 \times 2) + (\frac{1}{2} \times 9.8 \times 2^{2}) S = 100 + (\frac{1}{2} \times 9.8 \times 4) S = 100 + (9.8 \times 2) S = 100 + 19.6 = 119.6

Try it yourself before checking the explanation above.

If S = u t + \frac{1}{2} a t^{2} and u = 50, a = 9.8, t = 2, then the value of S is:
