Question

A particle has:

A.) an average acceleration of 6 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

B.) an average acceleration of 4 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

C.)an average acceleration of 12 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

D.)an average acceleration of 3 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

E.) an average acceleration of 2 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

Answer 1

Average acceleration =(Final velocity -Initial velocity)/ time taken

Put in the different values of final velocity ,initial velocity, time taken as given in various parts and check their correctness.
