Leaky bucket A 1-kg bucket resting on the ground init ally contains 6 kg of water. The bucket is lifted from the ground at a constant rate, and while it is rising, water leaks out of the bucket at a constant rate of 1 4 kg / m . How much work s required to lift the bucket a vertical distance of 8 m? Assume the weight of the rope used to raise the bucket is negligible.

Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.
The velocity of a particle moves along the x-axis and is given by the equation ds/dt = 40 - 3t^2 m/s. Calculate the acceleration at time t=2 s and t=4 s. Calculate also the total displacement at the given interval. Assume at t=0 s=5m.Write the solution using pen and draw the graph if needed.
