- This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A motorist starts from rest at Point A on a circular entrance ramp when t = 0, increases the speed of her automobile at a constant rate and enters the highway at Point B. Her speed continues to increase at the same rate until it reaches 85 km/h at Point C. Determine the speed at Point B. (You must provide an answer before moving on to the next part.) The speed at Point B is km/h. Note: please show step by step solution. Hence, double check the solution. For correction purposes!. I require handwritten working out please!. Kindly, please meticulously, check the image for conceptual understanding and for extra information purposes!. Also on occasions, I receive wrong answers!!. Please go through the question and working out step by step when you finish them. Appreciate your time!.arrow_forwardCar A is traveling at a constant speed of vA = 130 kph at a location where the speed limit is 100 kph. The police officer in car P observes this speed via radar. As Car A passes P, the car uniformly decelerates to the speed limit for 5 seconds and maintained the motion. Meanwhile, the police car begins to accelerate at the constant rate of 6 m/s2 until a velocity of 160 kph is achieved, and that speed is maintained. Determine the deceleration of car A to reach the speed limit,What is the distance traveled by the police to overtake car A, How long did it take for the police officer to overtake car A?arrow_forwardkm hr Q3/ Vehicle A is moving at a constant velocity VA 120- at a location where the speed limit is 100 km/h. The police officer in vehicle P observes this speed via radar. At the moment when A passes P. the police car begins to accelerate at the constant rate of 5 until a speed of 140 km/hr is achieved, and that speed is then maintained.

The driver of car A is traveling at va = 128 km/h as it passes P, but over the next 4.3 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.5 m/s? until a speed of 157 km/h is achieved, and that speed is then maintained.

- When the effect of aerodynamic drag is included, the y-acceleration of a baseball moving vertically upward is au = -g - kv², while the acceleration when the ball is moving downward is ad = -g + kv², where k is a positive constant and v is the speed in feet per second. If the ball is thrown upward at 94 ft/sec from essentially ground level, compute its maximum height h and its speed vf (a positive number) upon impact with the ground. Take k to be 0.0017 ft¹ and assume that g is constant. au=-g-ku² y 1 194 ft/sec Answers: h = Vf= i i ad=-g+kv2 h ft ft/secarrow_forwardCar A is traveling at a location where the speed limit is 100 km/h.

- Q16. As shown in the image below, the football player at A throws a football C with a velocity of VA = 19 m/s in the direction shown with = 60°. Determine the constant speed at which the player at B must run so that he can catch the football at the same elevation at which it was thrown. Player B is at d = 17 m away from A when A starts to throw the football. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s². V Answer: A Ro darrow_forwardCar A is traveling at a location where the speed limit is 100 km/h.
