A 200 kgkg weather rocket is loaded with 100 kgkg of fuel and fired straight up. It accelerates upward at 35 m/s2m/s2 for 32 ss, then runs out of fuel. Ignore any air resistance effects. What is the rocket's maximum altitude?

A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.

Problem 10: While watching the clouds pass by, you notice a European swallow flying horizontally at a height of h = 21.95 m. When the swallow is directly overhead, it drops an m = 10.5 kg coconut. Refer to the diagram. From your ornithological studies, you know that the air-speed of this particular species of swallow, while carrying such a load, is vo = 6.93 m/s. Neglect air resistance. Assume that your head is at the origin of the coordinate system. Part (a) Calculate the magnitude, in kilogram squared meters per second, of the angular momentum of the coconut, as observed by you, at the moment it is released directly overhead. L = 1597.19 L= 1597 V Correct! Part (b) Let 7 be the time-dependent position vector of the coconut with time measured from the instant it was released by the swallow. Enter an expression for its horizontal component as a function of time. r(1) = vot v Correct! Part (c) Enter an expression, in unit vector notation, for the time-dependent velocity vector, v(1), of…

Compressed air is used to fire a 46.0 g ball vertically upward from a 1.8-m-tall tube. The air exerts an upward force of 2.8 N on the ball as long as it is in the tube. How high (in m) does the ball go above the top of the tube, assuming that the acceleration due to gravity is 9.80 m/s2?
