Question

#1: (a) A Car is moving with a non-uniform velocity towards East.
Its velocity changes at different time intervals. Calculate the instantaneous
velocity at time 3 sec. The distance is given by equation
$2t {}^{2} - 4t$

​

Answer 1

Answer:

8m/s

Explanation:

s=2t²-4t

v=ds/dt=4t-4

t=3s

v at 3s= 4×3-4=8m/s
