The patient attends physiotherapy procedures at the clinic every day. Every morning he leaves the house at the same time and moves at a constant velocity 2,5 km/h. Once, leaving the house on time, the patient, on the 1/2 part of the way, remembered that he had forgotten the documents at home and decided to return home. How fast does the patient have to move in order to be in time for the beginning of the procedure? Please enter the correct units of measurement.
Referring to the figure, a truck drives a distance d=30.1m in the positive x direction in a time t1=17.2s, at which point the truck brakes, coming to rest in t2=8.13s. Part A: What is the truck's average velocity in the horizontal direction, in meters per second, during the t1 time period? Part B: Assuming the truck started from rest and moved with a constant acceleration, what was the acceleration, in meters per suqared second, during the time interval t1? Part C: What was the truck's instananeous velocity in the horizontal direction, in meters per second, when it began braking? And using the result from the previous answer, what was the truck's horizontal component of acceleration, in meters per squared second, during the braking period? Please explain how you got your answer in detail.

(A A person walks first at a constant speed of 4.80 m/s along a straight line from point to point and then back along the line from B to A at a constant speed of 3.05 m/s What is her average velocity over the entire trip? B m/s
A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 712 m, in a time tf = 163 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?
You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.
You and your family are going on a road trip to visit your recently married cousin in B.C. The total round trip distance is 2100 km. On the way to B.C., you encounter no setbacks and you are able to drive on average at a constant speed. On the way home from B.C., you encounter a snowstorm and your mom has to slow down to avoid getting into an accident. Thus, your average speed decreases by 10 km/h. If the total driving time was 42 hours, what was your average speed on the way to B.C.? Recall distance = speed x time.
A train is initially travelling along a straight track at a steady speed of 30 m s¯¹. At time t = 0.00 s a signal ahead turns red. It takes the driver 0.60 s to react and apply the brakes. Once the brakes are hit, the train decelerates with a constant acceleration of magnitude 9.0 m s2 until it comes to rest. What is the total distance travelled by the train in the period between the signal turning to red and the train coming to rest? Give your answer by entering a number (correct to an appropriate number of significant figures) in the empty box below. Total distance travelled = m.
A person hits a trampoline while moving downward with a speed of 9 m/s and rebounds a short time later with roughly the same speed upward. If the person is in contact with the trampoline for about 1.8 s, what are the magnitude and direction of the person’s average acceleration during this time interval? (Hint: You can ignore the effects due to gravity
A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for 420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to: O 0.20 m/s² O 0.14 m/s² O 0.19 m/s² 0.17 m/s² O 0.16 m/s²
A subway car leaves station A; it gains speed at the rate of 4 ft/s² for 6 s and then at the rate of 6 ft/s² until it has reached the speed of 48 ft/s. The car maintains the same speed until it approaches station B; brakes are then applied, giving the car a constant deceleration and bringing it to a stop in 6 s. The total running time from A to B is 40 s. Determine the distance between stations A and B.
