Question

what will be the velocity 3 sec after start. if the acceleration is 2cm/sec square

Answer 1

Answer:

In an ic engine intake temperature increases then the efficiency of engine is. If the intake temperature increases the efficiency will decrease... Because if the intake temperature increases the density of the air will reduce...by increasing the density of the intake of intake air only we can increase the efficiency..

Answer 2

Answer:

initial velocity (u) = 0

acceleration (a) = 2cm/s2

= 0.02 m/S2

time = 3s

We know that, v = u+at

v= 0+ 0.02 x 3

v = 0.06 m/s
