Question

a car traveling with the speed of 2 Ms -1 increases its speed to 10m S -1 in a time interval of 4 seconds what is the acceleration of the car​

Answer 1

u = 2 m/s

v = 10 m/s

t = 4 second

a = ?

a = v - u /t

a = 10 - 2 / 4

a = 8 / 4

a = 2 m / s²

please mark me the brainliest

Answer 2

Answer:

initial velocity=2 m/s

final velocity=10 m/s

time taken=4s

acceleration=v-u/t

=10-2/4

=2m/s²
