16 40 ft PROBLEM 11.72 A car and a truck are both traveling at the constant speed of 35 mi/h; the car is 40 ft behind the truck. The driver of the car wants to pass the truck, i.e., he wishes to place his car at B, 40 ft in front of the truck. and then resume the speed of 35 mi/h; The maximum acceleration of the car is 5ft/s and the maximum deceleration obtained by applying the brakes is 20 ft/s What is the shortest time in which the driver of the car can complete the passing operation if he does not at any time exceed a speed of 50mi/h? Draw the V-1 curve.
Q8. A 23-kg box was thrown onto a 34-kg cart with a speed of 9 m/s in the as shown. The cart is initially at rest. After the box lands on cart, it continues to move to the right at a speed of 2.5 m/s relative to the cart. Determine the speed of the cart. Neglect the friction between the cart and the ground. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. Your Answer: Answer units

An engine driver suddenly puts on his brake and shuts off steam when he is running at full speed; in the first second afteruwards the train travels 28 m and in the next second 26 m. Find (i) the original speed of the train, (ii) the time before it comes to rest, (iii) the distance it will travel in that interval, asuming the brake to cause a constant retardation. Find also the time the train will take, if it be 30 m long, to pass a spectator standing at a point 150 m ahead of the train at the instant when the brake was applied.
133. V=2.5 Total legth DEU Cope 16.667f4 ノ=ax(33 336 A man pulls a child up a tree, when the child is positioned at the ground the man and child are side by side. The man moves back with a v = 2.5 ft/sec and a = 0.1667 m/s?. When the man is 16.667 ft away calculate the child's speed/accel.
The trajectory of a soccer ball is analyzed when a goalkeeper decides to place it in the center of the field. Theball is kicked at a height of 1.20 meters measured from the ground with a direction of 25 degrees withrelative to the vertical. It was observed through cameras that the ball remained in the air for 2.4seconds. Determine:a- The speed with which the ball goes out.b- The hot horizontal distance it travels before hitting the ground.c- The maximum height the ball reaches.
2. At the figure shown, object A and B was released at the same time. Object A has an initial velocity of 3m/s . If object A and B strikes each other at a horizontal distance of 30m, detemine (a) initial velocity of B (b) time when the two objects reached the ground (c) vertical distance at which particle A is launched. A 45° aa = 1m/s² ag = 0.5m/s² B 60°
Kindly answer it as fast as you can.. and correctly.
The acceleration due to gravity at an altitude y above the surface of the earth can be expressed as where a and y are expressed in ft/s2 and feet, respectively. Using this expression, compute the height reached by a projectile fired vertically upward from the surface of the earth if its initial velocity is (a) 1800 ft/s, (b) 3000 ft/s, (c) 36,700 ft/s.
