(ii) | a cap- b cap | = 2sin theta
S
from t = 0, its position varying with time
as x=2t^3-3t^2+1.
(a) At which time instants is its velocity
zero?
(b) What is the velocity when it passes
through origin?
calculate the magnitude of
i) the velocity of the particle at t = 3s
ii) acceleration of the particle at t = 3s
iii)force(F) applied on the particle
Kindly solve the following question..
respectively. How many ergs are equal to one joule ?
t after starting is given by s=15t-0.4t^2.Find the time when the velocity of the body will be 7m/s
