2. Initially the 5-kg block is moving with a constant speed of 2 m/s around the circular path centered at 0 on the smooth horizontal plane. If a constant tangential force F = 5 N is applied to the block, determine its speed when t = 3 s. Neglect the size of the block. 1.5 m F = 5 N 2 m/s
The block has a mass of 40 kg and rests on the surface of the cart having a mass of 78 kg If the spring which is attached to the cart and not the block is compressed 0.2 m and the system is released from rest, determine the speed of the block with respect to the cart after the spring becomes undeformed. Neglect the mass of the wheels and the spring in the calculation. Also neglect friction. Take k = 310 N/m
A 10.5-Mg truck is resting on the deck of a barge which displaces 251 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge vrel = 5.1 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. t'red = 5.1 km/h 10.5 Mg 251 Mg- Answer: v = i km/h
The 11-lb block has a velocity of 3.83 ft/s when the force of F = (257.6t2) lb·ft/sec2 is applied. Determine the acceleration of the block when t = 2.08 s. The coefficient of kinetic friction at the surface is μk = 0.21. Answer is in ft/sec2.
The 1440-kg car has a velocity of 26 km/h up the 7-percent grade when the driver applies more power for 10 s to bring the car up to a speed of 64 km/h. Calculate the time average F of the total force tangent to the road exerted on the tires during the 10 s. Treat the car as a particle and neglect air resistance. 1 7 100 Answer: F = kN
The 20-g bullet is travelling at 400 m/s when it becomes embedded in the 2-kg stationary block. The coefficient of kinetic friction between the block and the plane is μk = 0.32. Determine the distance the block will slide before it stops. Express your answer to three significant figures and include the appropriate units.
A massless spring (with force constant k=300 N/m) connects a wall and a block. The system is initially at rest, with the spring unstretched. Mass of the bullet is 0.04 kg and its velocity is v0=110 m/s before it enters the block. Friction between block and surface is μ=0.4. What are the speed of the block and bullet after it enters the block mass of the block if the maximum force of the spring to the wall is Fj=60 N?
A 65 mg mass travels in a horizontal circular path at a speed of 2.2 m/s around the surface of the stationary drum. All surfaces are assumed to be frictionless. Determine the radius of the path, the normal force between the particle and the drum. ANS. a₁=ay=0 N=0.788 N an = 7.127 m/s² 36° r = 0.679 m.
