A rocket is launched at an angle of 53° above the horizontal with an initial speed of 75 m/s, as shown below. It moves for 25 s along its initial line of motion with an acceleration of 25 m/s². At this time, its engines fail, and the rocket proceeds to move as a free body.
a. What is the rocket's maximum altitude?
b. What is the rocket's total time of flight?
c. What is the rocket's horizontal range?
A 20-kg boy slides down a playground slide with a constant acceleration a = 1.1 m/s2 parallel to the surface of the slide. The boy starts sliding with an initial speed of v0=0. Refer to the figure.
a) write an expression for the child's speed squared, vf2, at the bottom of the slide in terms of a, v0, and the length of the slide, d.
b If the slide is 4.0 m long and the boy's final speed is vf=f = 5.0 m/s, what is his initial speed, in meters per second?
c) When starting from rest, how long, in seconds, does it take the boy to reach the bottom of the slide?
Scenario:
A landing party on the Moon discovers that the acceleration due to lunar gravity is g=1.6 ms2. An object is projected on the surface of the Moon in such a way as to provide an initial vertical component of velocity of 24 m/s, and a horizontal component of 32 m/s. *Reminder that a projectile is an object moving freely under the influence of gravity alone.
Procedure:
Answer the following questions using your knowledge of projectile motion.
a. What is the initial velocity, vo, of the object?
b. How long will the object remain in flight? (assume surface is flat)
c. How high will the object go?
d. How far will the object travel?
