Question

Q7.The displacement of the body x(in meters) varies with time t (in sec) as x=−2t/3t2+16t+2 find following what will the displacement when it comes to rest

Answer 1

Answer:

x = 23 t2 - 16t + 2 v = dx/dt v = 43 t - 16 when the body comes to rest : v ... The displacement x of a body varies with time t as x=32​t2−16t+2. ... (x is measured in meter and t in second). A . 6 s. B . 12 s. C . 18 s. D . ... 20 seconds for sunlight to reach the earth, find the distance between the Earth and the Sun.
