Question

6. A trolley while going on an inclined plane has an acceleration of 3 cm/s². What will be its velocity 2s after the
start?
a.6 cm/s
c. 6 m/s
b. 3.2 cm/s
d. 3.2 m/s
​

Answer 1

Answer:

Wow wonderful question I appreciate you Now I got interest on physcis the answer is down

Initial velocity is: u=0

time (t) = 2 sec

acceleration(a) is 3 cm‐²

v= u + at [ This is first equation of motion]

substitute the above numbers in equation

Then the answer 6cm/s
