Question

If a car is traveling at 8 ms−1 accelerates uniformly at 2 ms−2, its velocity after 5 seconds will be​

Answer 1

Answer:

18m\s-1

Explanation:

Explanation: by the help of the equation of  motion:

V = U+AT

step by step

u=8m\s-1

a=2m\s-2

t=5sec

V = U+AT

V = 8m\s-1 + 2m\s-2 * 5sec.

V = 8m\s-1 + 10m\s-1

V = 18m\s-1

Answer 2

Answer:

18 m/s

Explanation:

u=8m/s

a=2m/s sq.

t=5 sec

v=u+at......first equation of motion

v=8+(2×5)

v=8+10

v=18m/s

hope it helps....
