Question

a car moves with 20 metre per second and its velocity becomes 80 m per second after 6 seconds calculate its acceleration​

Answer 1

Answer:

Using newton' first equation of motion. v=u+at. v is the final velocity , a is acceleration,t is time, u is the initial velocity.hence

80=20+a×6

80–20=6a

60=6a

a=60/6

a=10m/s²

Please mark me branlist

Answer 2

Answer:

final velocity(v) - initial velocity / time

so : 80 - 20/6

thus your answer will be 10 m/s
