At a football tryout, a player runs a 40-yard dash in t, = 4.70 seconds. If the reaches his maximum speed at the 14-yard mark L constant acceleration and then maintains that speed for the remainder of the run, determine his acceleration over the first 14 his maximum speed, and the time duration of the acceleration.

Task II Samir tests his new motorcycle by racing with Ahmad. Both start from rest, but Samir leaves the starting line 2.00 s after Ahmad does. Ahmad moves with a constant acceleration of 3.0 m/s2, while Samir maintains an acceleration of 4.0m/s2. Find the time at which Samir overtakes Ahmad, the distance that Samir travels before catching Ahmad, and the velocity of both cars at the instant Samir overtakes Ahmad.

3. As shown in the image below, if the distance d = 9.0 ft, and at this point the speed of the crate A is 14.5 ft/s, which is increasing at a rate of 4.3 ft/s², determine the magnitude of the acceleration (in unit of ft/s2) of the crate at this instant. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. y = 16** d Your Answer: Answer

QUESTION 11 An air missile falls vertically into the ocean and enters the sea water with velocity 148 m s¯1. Its deceleration a (m-s-2) wthin the water is a function of its velocity v (m-s-1) according to the expression a=-5v Determine the sea depth at which the velocity of the missile becomes zero by assuming straight vertical motion. Provide only the numerical value (in metres) to zero decimal places and do not include the units in the answer box.

Don't skip the steps. Thanks in advance

Please show all work!!

Q1/ A car starts from rest and moves with a constant acceleration of 1.5 m/s until it achieves a velocity of 25 m/s. It then travels with constant velocity for 60 seconds. Determine the average speed and the total distance traveled.

Starting from rest, a particle moving in a straight line has an acceleration of a = (2t - 6) m/s^2, where t is in seconds. Determine the particle's velocity and position 4s after. Write your answer in the format (v=___ft/s; x=___ft)

This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The elevator E shown starts from rest and moves upward with a constant acceleration. The counterweight W moves 32 ft in 5 s.    Determine the velocity of the elevator after 5 s.    The velocity of the elevator after 5 s is ft/s ↑.?   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!.
