Question

application of calculus-topic
the velocity of a car travelling on a straight road is given by the equation V=9+8t-t^2 where V is in meter per second and t in second .the instantaneous acceleration when t=5s is

Answer 1

Explanation:

ANSWER

v=9+8t−t

2

, Inst.acc

n

=a=dv/dt=8−2t

∴ instantaneous acceleration at t=5sec=8−2×5=−2m/s
