NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, in terms of time is given by h = − 4.9 t^ 2 + 94 t + 297 . How high is the rocket after 3 seconds? How high was the rocket when it was initially launched?

Assume a rocket is launched from a platform that is 20 meters high at angle of 53 degrees. While the rocket still has gasoline, it uniformly accelerates, maintains a launch angle relative to the ground, for four seconds and reaches a velocity of one hundred meters per second starting from rest. You may neglect any air resistance. Part 1: What is the max height the rocket can have before it falls back to ground? Part 2: How much time does...

8.8.47 A rocket is launched from the top of an 8-ft platform. Its initial velocity is 144 ft per sec. It is launched at an angle of 60 with respect to the ground, (a) Find the rectangular equation that models its path. What type of path does the rocket follow? (b) Determine the total flight time and the horizontal distance the rocket travels. (a) Using y to indicate the height of the rocket and x to...

A baseball (a projectile) is launched from a height of 2 meters above the ground at a speed of 31 m/s at an of 28 degrees above the horizontal. The ball is directly hit a fielder who will catch the ball and the fielder is initially angle plate). If his reaction time is 0.30 seconds (time before he starts to move), what is the minimum speed he much run, in m/s, such that he catches the ball 2 meters above...
2. An object of 5 kg is released from rest 1000 meters above the ground level...
2. An object of 5 kg is released from rest 1000 meters above the ground level and allowed to fall under the influence of gravity. Assuming that the force due to air resistance is proportional to the velocity of the object with proportionality constant k = 50 kg/sec determine the formula for the velocity of the object 3. A rocket having an initial mass mo kg is launched vertically from the surface of the Earth. The rocket expels gas at...
