A particle starts from rest and accelerates uniformly in a straight line. The particle travels a distance of 6.70 m in 2.50 s . How fast, in miles/hour (mph), will the particle be traveling after a time of 4.50 s has elapsed? Assume 1 mile=1609.34 m. Express your answer using three significant figures.
A particle starts from rest and travels along a straight line with an acceleration a = (30 – 0.2v) ft/s?, where v is in ft/s. Determine the time when the velocity of the particle is v = 30 ft/s.
5. Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 5.0 m/s Which one of the following statements accurately describes the motion of this particle? A) The particle travels 5.0 m during each second. B) The particle travels 5.0 m only during the first second. C) The speed of the particle increases by 5.0 m/s during each second. D) The acceleration of the particle increases by 5.0 m/s during each second....
