The figure depicts two pucks on a frictionless table. Puck 2 is four times as massive as puck 1. Starting from rest, the pucks are pushed by two equal forces. 1-Which pucks will have the grater kinetic energy upon reaching the finish line? 2- Which puck will reach the finish time first ?
Block A with a weight of 100N (mA=10kg) moves to the right (vA=1 m/s) at the moment shown in the figure. Since the kinetic friction coefficient between the surface and block A is μk=0.2, find the speed of block B when it moves 2 meters its weight is 200N (mB=20kg)
A 0.525-oz model rocket is launched vertically from rest at time t = 0 with a constant thrust of 0.9 lb for 0.3 s and no thrust for t > 0.3 s. Neglect air resistance and the decrease in mass of the rocket. Find the time required to reach the maximum height
The super-container vessel has a total mass displacement of 23000 long tons. This vessel towed by a tugboat with α=20⁰ angle with horizontal. If a constant tension is applied as F=320 kN by the tugboat, please calculate the time to bring the vessel to a speed of 2 knot from the rest. At these low speeds, please neglect the hull resistance that created by the motion. Note: (1 long tons = 1016.05 kg, 1 knot=1.151 mi/hr= 0.5144 m/s)
A speedboat with a mass of 529 kg (including the driver) is tethered to a fixed buoy by a strong 28.3 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m)×v2, where v denotes the boat's speed. Ignore any drag force on the cable. What is the force of the engine?
A 4-kg block rests on a smooth surface and is acted upon by force F, as shown in the figure. What is the value of the force F if the block accelerates at 15 m/s2
In a 300-rough incline, a 1.25 kg block is initially at rest beside a spring that is compressed by 24 cm as shown in the figure below. The spring has a spring constant of 180 N/m and the coefficient of sliding friction between the incline and the block is 0.23. When the spring is released, (a) how far up the incline (with respect to its initial position) will the block slide before sliding back? (b) What is the speed of the block at the instant it is 0.34 m from its initial position?
