The displace ment of a body at any time t after starting is given by `s=10t-(1)/(2)(0.2)t^2`. The velocity of the body is zero after:

The displacement of a body at any time t after starting is given by s=15t-0.4t^(2) . The velocity of the body will be 7ms^(-1) after time :

1) The displacement of a body at any time t after starting is given by s=15t-0.4t^(2) .The velocity of the body will be 7ms^(-1) after time = ? 2) for the previous question,the acceleration of the particles at any time is:
