A car traveling along a straight highway accelerates uniformly from 30 km / h to 60 km / h in 1 minute.

A car traveling along a straight highway accelerates uniformly from 30 km / h to 60 km / h in 1 minute. What is the value of acceleration, with uniformly accelerated motion.

We use the formula a = (v – v0) / t to calculate the acceleration of the car.

We have:

v = 60 km / h = 60,000/3600 = 50/3 m / s,

v0 = 30 km / h = 30,000/3600 = 25/3 m / s,

t = 1 min = 60 s.

Let’s calculate the acceleration using this data:

a = (50/3 – 25/3) / 60 = 5/36 ≈ 0.14 m / s².

Answer: a ≈ 0.14 m / s².
