6. Two rockets start from rest at the same elevation. Rocket A accelerates vertically at 20 m/s for 12 s and then maintains a constant speed. Rocket B accelerates at 10 m/s2 until reaching a constant speed of 150 m/s a. Construct the a-t, v-t, and s-t graphs for each rocket until t20 s b. What is the distance between the rockets when t 20 s?
A low-flying crop-duster A is moving with a constant speed of 40 m/s in the horizontal circle of radius 300 m. As it passes the twelve-o'clock position shown at time t = 0, car B starts from rest from the position shown and accelerates along the straight
A low-flying cropduster A is moving with a constant speed of 40 m/s in the horizontal circle of radius 300 m. As it passes the twelve-o'clock position shown at time t = 0 car B starts from rest from the position shown and accelerates along the straight road at the constant rate of 3m / (s ^ 2) until it reaches a speed of 30m / s after which it maintains that constant speed.

Problem 1) A car starts from rest at x 0 and 0, travelling in a straight line. The car speeds up and then slows down until it comes back to rest at a distance of 0.900 km from where it started. For the first quarter of the distance, its acceleration is +2.25 m/s2, while for the last three quarters of the distance its acceleration is -0.750 m/s2. (a) Find the travel time for the entire trip. (b) Find the maximum...
