Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the bow back 50 cm and holds it in position with a force of 150 N. If the mass of the arrow is 50 g and the “spring” is massless, what is the speed of the arrow immediately after it leaves the bow?

1. It's 5:00 PM and Kurdapya needs to finish her physics module, one of the problems tates that a rocket and a spacecraft were attached and has a combined mass of 3.8 × 10⁵kg and is to reach a speed of 12.3 km/s, she needs to know how much kinetic energy will it have. 2. The next day, Kurdapya craved for some riped guava fruit. She has to climb the guava tree however she realized that she is already 65 kg and the tree is 7.2 meters high. Let us calculate the power required for her to climb the tree in 15 seconds.

A uranium-238 nucleus undergoes a radioactive decay, 238 U 234Th + 4He. The masses are approximately 238, 234 and 4 u, where u = the atomic mass unit. The U nucleus is initially at rest. Suppose the He nucleus has speed v. Then what is the kinetic energy of the Th nucleus? Parameters: ] u = 1.66 x 10-27 kg; v = 9.000×106 m/s.
