The car moves on a straight section of the highway with a constant acceleration of 0.2 m / s which is equal to the speed of the car in 10 s, if at the initial moment of time at zero = 20 m / s

Let at the initial moment of time (at t₀ = 0 s) a car moving uniformly accelerated on a straight-line section of the highway had an initial speed v₀ = 20 m / s. From the condition of the problem it is known that the car was moving with a constant acceleration equal to a = 0.2 m / s ^ 2. To find what the speed of the car is equal to after a time interval t = 10 s, from the beginning of the movement, we use the formula: v = v₀ + a ∙ t. Substitute the values of physical quantities in the calculation formula and perform the calculations:
v = 20 m / s + 0.2 m / s ^ 2 ∙ 10 s.
v = 40 m / s.
Answer: the vehicle speed has become 40 m / s.
