Constant Acceleration Kinematics: 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.
Bottles of perfume sometimes have thick glass (n = 1.5) walls which give the impression the volume is larger than it really is. Assume a cylindrical bottle with an inner radius of 1.0 cm and an outer radius of 2.0 cm. What percentage of the apparent volume is the real volume?
A. 95% B. 60% C. 80% D. 64% E. 75%
The place in a planet's orbit that is closest to the Sun is called:
