Question

the speed pf an object at the end of 4 succesive seconds is 20, 25,30,35 meters per second respectively. the acceleration of these objects is.​

Answer 1

Answer:

5m/s^2

Explanation:

By taking any 2 of these velocities and their given time intervals respectively and applying

(v-u)/t we get:

(25-20)/1

[since time period for change in velocity is 1 sec in this case]

5 m/s^2 is the answer

{you might as well take any two velocities out of all 4 and get the same answer since this is the case of uniform acceleration but do check that the time interval is correct with respect to change in velocity}
