- PLEASE ANSWER ASAP: A 4.61m-tall truck is moving an initial speed of 15.32m/s due West with an acceleration of 0.22 m/s^2 with a 1.66m- person standing at the top of a truck. After 17.93s, the man throws a ball to the ground at shoulder level perpendicular to the left of the truck's direction with an initial velocity of 23.53 m/s at an angle of 42.80° above the horizontal. Assuming shoulder level is 80% of the total height and negligible air resistance, determine the magnitude and direction of the displacement of the ball upon impact. [Use positive angle and CCW]You kick a ball with an intial velocity whose magnitude is 11.9 m/s and whose direction is 49°. How far away is it when it lands? A cannonball is fired with an initial velocity whose magnitude is 2194.8 ft/s, and whose direction is 82°. How many minutes is it in the air? You are driving along, when you see an obstacle in the road ahead. You slam on your brakes and your car begins sliding at a constant rate of deceleration. It takes your car 2.7 s to slide a halt in 16.9 m. How fast were you moving (in meters per second) before you hit your brakes?A coin is thrown from a moving car. While it is in flight, it is not true that its what is the answer? a) speed changes, b) acceleration changes, c) direction relative to the car changes, d) direction relative to the ground changes,

Find the magnitude and the direction below the horizon?An unsuspecting bird is coasting along in an easterly direction at 2.00 mph when a strong wind from the south imparts a constant acceleration of 0.300 m/s2 . If the wind's acceleration lasts for 3.40 s , find the magnitude ? and direction ?(measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. Assume that the bird is originally travelling in the +? direction and that there are 1609 m in 1 mi . r=3.499m ?= 27.71∘ Now, assume the same bird is moving along again at 2.00 mph in an easterly direction, but this time, the acceleration given by the wind is at a ?=37.0° angle to the original direction of motion, measured counterclockwise from the easterly direction. If the magnitude of the acceleration is 0.300 m/s2 , find the displacement vector ?⃗ and the angle of the displacement ?1 . Enter the components of the vector, ?? and ?? , and the angle. Assume the time interval is still 3.40 s . ?⃗=???̂+???̂Landing with a speed of 71.4 m>s, and traveling due south, ajet comes to rest in 949 m.

- A jet airliner is moving east at 225 m/s, but experiences a head wind heading north at 50.0 m/s. b) When determining speed of the airliner, does it have to do with calculating speed, based on the two "givens" to calculate the hypotenuse of a right triangle?A softball is hit with an initial velocity of 28.5 m/s at an angle of 60.3° above the horizontal and impacts the top of the outfield fence 4.91 s later. Assuming the initial height of the softball was 0.500 m above (level) ground, what are the ball's horizontal and vertical displacements? (Use 9.81 m/s2 for the acceleration due to gravity.)Coast Guard rescue swimmers are trained toleap from helicopters into the sea to save boaters in distress. Therescuers like to step off their helicopter when it is “ten and ten,”which means that it is ten feet above the water and moving forward horizontally at ten knots. What are (a) the speed and (b) thedirection of motion as a rescue swimmer enters the water following a ten and ten jump?
