The displacement x(t) of a particle from the origin at time t, t≥0, is x(t)=t^3+3t(t-3)+10. find min velocity?

0 m/s

Explanation:

given,

x(t)=t^3+3 t (t-3)+10

velocity

.............(1)

now, differentiating both side for minimum velocity calculation

now, equating derivative equal to zero

t = -1

again differentiating

hence, at t = -1 velocity will be minimum

now, inserting value of t in equation 1

 v = 0 m/s

hence, minimum velocity is equal to 0 m/s

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
