Question

A particle changes its velocity from 5 m per second to 8 m per second in 9 sec, Find acceleration of the particle​

Answer 1

ɪɴᴛɪᴀʟ ᴠᴇʟᴏᴄɪᴛʏ=ᴠ1=5ᴍ/sᴇᴀsᴛ ᴡᴀʀᴅs  

                                 

ᴛʜᴇɴ ᴀғᴛᴇʀ ᴛɪᴍᴇ ᴛ=10sᴇᴄ              

                                       

ᴠ2=5ᴍ/s ɴᴏʀᴛʜ ᴡᴀʀᴅs                                    

                                                                

δᴠ=ᴠ12+ᴠ22

         =25+25

         =52

2 sums dude which is easy u can try

l hope it will help u ☺️✌️☺️

Answer 2

Answer:

Explanation:

Heya!!

--------

Given that ,

Initial velocity u = 20 m/s.

Time t= 5 seconds

Acceleration = 2m/s2.

Final velocity v =?

Using first equAtion of motion

V = u + AT

V = 20 + 2×5

V = 30 m/s
