of 20km/hr accelerate with an acceleration
of 0.10 ms ^-2 After what time will
it velocity be 38 km/hr​

Answer 1

Answer:

50 seconds

Step-by-step explanation:

u = 5.5 m/s (20 km/h)

v = 10.5 (38 km/h)

a = 0.10 m/s

as we know

a= v- u/t

this could be written as

t= v - u/ a

= 10.5 - 5.5/0.10

= 5/0.10

= 50 s
