Motion in a Straight Line: RE-NEET 2026

Medium· Average Velocity and Average Speed (Average Speed)· +4 / −1
Consider a particle moving along a straight line, whose position as a function of time is given by s(t)=αt2−βt+γs(t) = \alpha t^2 - \beta t + \gamma, where α=1 ms−2\alpha = 1\ \mathrm{ms^{-2}}, β=6 ms−1\beta = 6\ \mathrm{ms^{-1}} and γ=5 m\gamma = 5\ \mathrm{m}. The average speed of the particle, in ms−1\mathrm{ms^{-1}} from t=0t = 0 to t=6t = 6 s is:
