Question

an object moves along a straight line with an acceleration of 2 metre per second square if its initial speed is 10 metre per second what will be its speed 5 second later​

Answer 1

Answer:

answer is 20

Explanation:

as we know that

v=u+at

then,

v=10+(5×2)

v=10+10

v=20

Your Answer

Answer 2

Answer:

acceleration (a)=2m/s²

initial speed (u) = 10 m/s

time (t) = 5s

Applying equations no. 1 of motion

v=u+at

v=10+2*5

v= 20 m/s
