In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.47 kg) and embeds itself in block 2 (mass 2.02 kg). The blocks end up with speeds v1 = 0.590 m/s and v2 = 1.45 ?
The system in the figure below is in equilibrium, with the string in the center exactly horizontal. Block A weighs 37.0 N, block B weighs 47.0 N, and angle φ is 37.0˚. What are
(a) tension T1, (b) tension T2, (c) tension T3, and (d) angle θ. ?
How to sketch this graph and describe the motion ? For example, describe in each time interval the motion involved in each actual graph: whether it is constant velocity/acceleration, slowdown/speedup, stationary, forward/backward ?

How do you evaluate the sum represented by #sum_(k=50)^300k^3#?
Consider the integral given by [a,b]=[0,4].
(a) Find an approximation to this integral by using a Riemann sum with right endpoints and n = 8. Your answer should be correct to four decimal places.
