A train has a length of 104 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 8.14 s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 39.9 s, the car is again at the...
A train has a length of 107 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 11.3 s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 37.3 s, the car is again at the...
PB#1 : A train starts from rest (at position zero) and moves with constant acceleration. On first observation, the velocity is 20 m/s, and 80 s later the velocity is 60 m/s. At 80 s, calculate the position at t = 20m/s, average velocity, and constant acceleration over the interval.
12) A sprinter running a 100 m race starts at rest and accelerates at constant acceleration A for 3.0 seconds and then maintains a constant velocity. In terms of A, what is the position of the runner after 3.0 seconds? What is A if the sprinter finishes the race in 12.0 seconds? 13) What force is needed to accelerate a 30.0 lb block at 2.2 m/s2? 14) What force is needed to stop a 1500 kg car in 40 m...
A train starts from rest and accelerates uniformly until it has traveled 2.1 km and acquired a forward velocity of 24 m/s. The train then moves at a constant velocity of 24 m/s for 400 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The distance traveled by the train while slowing down is closest to A) 4.4 km. B) 4.2 km C) 4.0 km D) 3.8 km E) 3.6 km
