1. A skateboarder is trying to record his flight time into the lake from the ramp shown below. The cliff is about 30 ft. high and he is traveling at a constant speed of 35 mph. The angle of the ramp is 55° from the horizontal. a. Calculate how long the skateboarder will be in the air (in seconds). [Ans. to check: 3.2 s] b. What is the horizontal distance he travels (in feet)? In other words, find the value of "d". [Ans. to check: 94.2 ft] 50=559 H=30ft 19

3. An engineer is designing the runway for an airport. Of the planes that will use theairport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed forthis plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length for the runway?
Using graphical method solve this problem: Suppose you first walk A in a direction of B west of north then C in a direction D south of west. You rest for 20 minutes and started to compute the distance you traveled. Take A, B, C and D found in the table below. (You may use scale such as 1cm = 2m in your drawing) C. What is the angle between AC ? D. What is the angle between your first walk A to the resultant R?
m m An overzealous driver wishes to get from one stoplight to the next as fast as possible. Her car's maximum acceleration is 2.5 and maximum deceleration is 4 She will start from rest at the first stoplight s² s² and come to a stop at the second stoplight. The stoplights are 200 meters apart: a.) What is the miminum amount of time (in seconds) required for her to reach the next stop light? b.) What is the maximum speed (in m/s) her car reaches?
A certain hawk can fly horizontally (i.e., not diving) at a maximum speed of 80.0 km/hr. The hawk takes off from rest at the edge of a cliff, heading east, and accelerates at a rate of 1.25 m/s2 . a. How long does it take to reach its top speed? b. How far does it travel during this time? c. Once the hawk has reached its top speed, it turns 30 degrees to the south and flies at a constant speed for another 30 seconds. How far is it from the cliff at the end of this journey?
Shaun boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple revolutions. The Ferris wheel rotates at a constant angular speed. Let h represent Shaun's height above the center of the Ferris wheel (in feet) and let t represent the number of mintues since the ride started. a. Suppose the radius of the Ferris wheel is 20 feet and the Ferris wheel rotates at 1 radian per minute.

1. For this series of 3 questions, a jet bike is moving along a straight road with the speed described by the v-s function v(s) = 2. s2/3, (v in [m/s] and sin [m]). Your final goal is to determine the velocity (v) at a specified time. But before that, you need to answer some other questions. 3) determine the velocity (v) when the time t = 7.1 s. Your answer must include 2 places after the decimal point, and the proper unit. Your Answer: Answer units
UPVOTE will be given! Please write the complete solutions legibly. No long explanation needed. Answer in 2 decimal places. Dynamics of Rigid Bodies A particle moves that is defined by the parametric equations given below (where x and y are in meters, and t is in seconds). Compute the radial component of the velocity (m/s) at t = 2 seconds. x = 3t2 - 1 ; y = t3 - 3t2 + t - 3
