Question 20

An 10,000.0 kg truck starts off from rest and reaches a velocity of 16.1 m/s in 4.6
seconds.
What is the truck's accelerſation? Round your answer to one decimal.

Answer 1

`\huge\boxed{\sf a = 3.5 \ m/s^2}`

Step-by-step explanation:

Given data:

Initial velocity =
`V_i` = 0 m/s

Final velocity =
`V_f` = 16.1 m.s

Time = t = 4.5 seconds

Required:

Acceleration = a = ?

Formula:

`\displaystyle a = (V_f-V_i)/(t)`

Solution:

Put the given data in the above formula.

`\displaystyle a = (16.1-0)/(4.6) \\\\a = (16.1)/(4.6) \\\\a = 3.5 \ m/s^2\\\\\rule[225]{225}{2}`
