Q23. As shown in the image below, the force acting on the 5-kg crate is a function of time. The coefficient of kinetic friction between the crate and the surface is uk= 0.14. Determine the crate's speed at t= 2.1 s if its initial speed v1 = 2.9 m/s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s2. F = (201² +30)N (t in second) F. 30 V1 Your Answer: Answer units

Problem-2 A train starts from rest at station A and accelerates at 0.5m/s? for 60 s. Afterwards it travels with a constant velocity for 15 min. It then decelerates at 1m/s? until it is brought to rest at station B. Determine the distance between the stations.
