Question

hey guys can u help me how to solve acceleration problem?

Answer 1

yes i can wats the problem

Answer 2

well to find the acceleration you can use the formula acceleration=change in velocity/time taken

Answer 3

acceleration=initial velocity-final velocity/time taken

Answer 4

so did it help

Answer 5

if the said constant velocity is it the same formula

Answer 6

wat do you mean

Answer 7

constant acceleration

Answer 8

do you want me to do you a problem

Answer 9

so you can understand

Answer 10

yah

Answer 11

q1)a car starts from rest .its velocity becomes 20ms-1 in 8s .find its acceleration.

Answer 12

solution:


initial velocity=0 ms-1 (because the car is starting from rest)
final velocity= 20 ms-1
time taken= 8s

as a=vi-vf/t
a=20ms-1-0ms-1/8s
=2.5 ms-2
so the acceleration is 2.5ms-2

Answer 13

so r u good

Answer 14

ok thanks

Answer 15

can u give me a medal if i really helped u

Answer 16

please

Answer 17
