- One of my questions got solved and helped me so much thank you! Here’s another one please. Two trains are 9.82km apart. They travel in opposite directions, to each other. Train A has a speed of 5.87 km/h at departure and an acceleration of 0.29m/s squared. Train B has a speed of 20.3m/s at the start and an acceleration of 0.69m/s squared. B. Determine when the trains meet.A sphere is fired downward into a medium with an initial speed of 37 m/ S. If it experiences a deceleration of a=(-6t)m/s^2, where t is in seconds, determine the distance traveled before it stops. Express your answer to three significant figures and include the appropriate unitsAn object's position is given by r(t) = [a + ßt] î+ [y+ot²] 3 where • d = 2.86 m B 3.5 m/s • Ύ 3.15 m • σ = -4.1 m/s² t = 7.2 s = What is its speed v at t = 7.2 s?

How many seconds does it take for the signal to reach the Earth?A dog initially at rest, starts running inside a circular track with a 40π m circumference. The dog's acceleration tangent to its path is defined by the function at = 0.1t^2 + 0.4t. What is the total distance ran by the dog after t = 10 s?A car drives around a circular track of diameter 161 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 256 degrees around, what is the magnitude of the car s average acceleration? Hint: Do not calculate instantenous accelleration. Instead calculte the average acceleration over the fraction of a complete lap. Average acceleration equals change in velocity divided by change in time, and that this is a two-dimensional situation so you'll have to calculate the x and y components of the average acceleration first and then figure out the magnitude. Remember also that ax = Δvx/Δt and ay = Δvy/Δt. 0 m/s^2 27.91 m/s^2 13.96 m/s^2 9.84 m/s^2
