Question

15. If Q = 4v3 + 3v2, then the value of 'V' for maximum 'Q' is 1 (1) O (2) 2 1 (3) (4) None 2 16. If a man has a velocity varying with time (t) is given as v = 3t2, then the velocity of the man at time t = 3 s is (1) 18 m/s (2) 9 m/s (3) 27 m/s (4) 36 m/s 17. If y = 3t2 – 4t; then minima of y will be at t equals to (1) 3/2 (2) 3/4 (3) 2/3 (4) 4/3 18. If y = sin(t), then second differentiation of y with respect to t will be (1) 2t cos(t2) (2) 2 cos (t2) - 4t2 sin (12) (3) 4 t2 sin (t2) (4) 2 cos (t2) ta Medical In​
