Neco 2025 Physics Question 38
Practice objective / multiple choice question 38 from the 2025 Neco Physics examination.
A particle of mass 2.0\,kg moves along a straight line. Its velocity\-time graph for the first 7\,s is as follows: from t = 0 to 2\,s the velocity increases uniformly from 0 to 4\,m\,s^{-1}; from t = 2 to 5\,s the velocity remains constant at 4\,m\,s^{-1}; from t = 5 to 7\,s the velocity decreases uniformly to 0. After t = 7\,s the particle continues with a constant speed of 2.0\,m\,s^{-1} until the total distance travelled from the start reaches 30.0\,m. How many seconds does the particle travel after t = 7\,s? Give your answer to one decimal place.
