Question
1. A particle has an initial speed of 60 kph. If it experiences a deceleration of a = (- 6t ^ 3 + 4t) * m / s * 2 where t is in seconds, determine its velocity, after it has traveled 100 m in m/s. How much time does this take in second(s)? 2. The dragster starts from rest and travels along a straight track with an acceleration-deceleration described by the graph. Construct the v-s graph for 0
1. A particle has an initial speed of 60 kph. If it experiences a deceleration of a = (-6t'+4t) m/s2,
where t is in seconds, determine its velocity, after it has traveled 100 m in m/s. How much time
does this take in second(s)?
2. The dragster starts from rest and travels along a straight track with an acceleration-deceleration
described by the graph. Construct the v-s graph for 0ssss', and determine the distance s'
traveled before the dragster again comes to rest.
