Use a quadratic function to model projectile motion Question A model rocket is launched directly upward at a speed of 28 meters per second from a height of 12 meters. The function f(t) = -4.96 +28+12, models the relationship between the height of the rocket and the time after launch, t, in seconds. When, in seconds after launch, will the rocket hit the ground? Do not round until the final answer. Then round your answer to two decimal places. Provide...
A firework is launched straight upward from a height of 1 meter. The acceleration function for the firework is given below: a(t) = e^t + cos(t) meters per second squared where t is time since thefirework launched. (a) Find the velocity and position functions for the firework. (b) What is the net change of thefirework's position after 3 seconds?
2.4) [2.53 in text book] A model rocket is launched straight upward with an initial speed of 50.0 m/s.

A small rocket to gather weather data is launched straight up. Several seconds into the flight, its velocity is 100 m/s and it is accelerating at 19 m/s^2. At this instant, the rocket's mass is 47 kg and it is losing mass at the rate of 0.50 kg/s as it bums fuel. What is the net force on the rocket? Express your answer to two significant figures and include the appropriate units.
A faulty model rocket moves in the xy-plane (the positive y-direction is vertically upward). The rocket's acceleration has components ax(t)=αt2 and ay(t)=β−γt, where α = 2.50 m/s4, β = 9.00 m/s2, and γ = 1.40 m/s3. At t=0 the rocket is at the origin and has velocity v 0=v0xi^+v0yj^ with v0x = 1.00 m/s and v0y = 7.00 m/s. a. Calculate the velocity vector as a function of time. Express your answer in terms of v0x, v0y, β, γ, and...
