- There is one part to this question. I need to know the m/s. Thank you!A motorboat, operating at full throttle, made a trip 4 miles upstream (against a constant current) in 15 minutes. The return trip (with the same current and at full throttle) took 12 minutes. Find the speed of the current and the equivalent speed of the boat in still water.A rocket begins at rest in outer space. Its thrusters ignite and it accelerates at 7 m/s2 for 41 s. After that, the thrusters shut off and the rocket coasts for an additional 84 s. How far does the rocket travel during both of these time periods combined, in m? (Please answer to the fourth decimal place - i.e 14.3225)

- A transport plane travelling at a steady speed of 64 ms-1 and an altitude of 68 m, releases a parcel when it is directly above a point Q on level ground. a) What is the time of flight (in s) of the parcel? b) What is the horizontal distance (in m) from Q to the point of impact? c) What is the speed (in ms-1) of impact of the parcel?A pig on roller skates is moving with an initial velocity of -10 m/s and is accelerating at a rate of 2m/s/s, therefore the pig is __________during the next 2 seconds.I need the answer by detail
- Please help with the solution to this problem using (km/s). I know we will use Hohmann Transfer and a combined plane change. In the opening scene of the movie “Gravity” Dr Ryan Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) are required to transit from the Hubble Space Telescope (Altitude 600 km, 28.5 degree inclination) to the International Space Station (Altitude 400 km, 51.6 degree inclination) using nothing but their Manned Maneuvering Units (MMU). An MMU has a delta V capability of about 30 m/s, and it would be impossible to perform this maneuver with so little delta V, but… a.) How much delta V would be required for this maneuver? b.) What if the maneuver did not require an inclination change (altitude change only?)A small, battery-powered, electric motorboat that can travel at a speed of 1.80 m/s in still water is operating in a river with a flow speed of 1.35 m/s. For each of the following two cases, determine the requested information for a river that is 220 m wide. (a) Case 1: when the boat is pointed straight across the river, determine the speed Vbl of the boat as viewed by someone on land, the distance d the boat is swept downstream before reaching the other side, and the time t it takes the boat to make the crossing. Vbl = m/s d = t1 = (b) Case 2: if the boat operator wants to land the boat straight across the river from the launch site, determine the speed Vbl of the boat as viewed by someone on land, the angle ß upstream at which the boat should be pointed, and the time t2 it takes the boat to make the crossing. Vbl = m/s ß = t2 = SCould I have help with this physics problem
