You are a member of an alpine rescue team and must get a box of
supplies, with mass 2.10 kg , up an incline of constant slope angle
30.0 ∘ so that it reaches a stranded skier who is a vertical
distance 2.80 m above the bottom of the incline. There is some
friction present; the kinetic coefficient of friction is
6.00×10−2. Since you can't walk up the incline, you give
the box a push that gives it an initial...

iPad 3:59 PM * 48%. 115:33:08 Exit 1 A rifle is fired straight up, and the bullet leaves the rifle with an initial velocity magnitude of 525 m/s. After 4.15 s, the velocity is 482 m/s. At what rate (in m/s2) is the bullet decelerated? (Recall that a negative sign denotes negative acceleration, or deceleration.) Enter answer 2 A rock thrown straight up climbs for 3.50 s, then falls to the ground. Neglecting air resistance, with what velocity (in m/s)...

You are a member of an alpine rescue team and must get a box of supplies, with mass 2.60 kg , up an incline of constant slope angle 30.0 ∘ so that it reaches a stranded skier who is a vertical distance 3.30 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial...

Write three object-oriented classes to simulate your own kind of team in which a senior member type can give orders to a junior member type object, but both senior and junior members are team members. So, there is a general team member type, but also two specific types that inherit from that general type: one senior and one junior. Write a Python object-oriented class definition that is a generic member of your team. For this writeup we call it X....

Question 12 A bullet is fired horizontally from a handgun at a target 100.0 m away. If the initial speed of the bullet as it leaves the gun is 300.0 m/s, how far vertically will the bullet have dropped by the time it hits the target? Ignore the effects of air resistance NOTE TO PHYS 1A STUDENTS: This problem originally had an error, so it will not be counted in the HW score whether or not you already entered an...
