Q.2. A block of mass m = 0.5 kg is pushed against a horizontal spring of spring %3D constant k = 450 N/m and negligible mass. The spring is compressed a distance x from equilibrium, and then released from rest. The block travels along a frictionless horizontal surface and reaches point B with a speed vg = 12 m/s. After reaching B, at the bottom of a vertical circular track of radius R = 1 m, the block continues %3D to move up the track. Take g = 10 m/s². The normal force exerted by the track %3D on the block at B is: a. N = 103 N b. N = 77 N c. N = 133 N B. d. N = 67 N
An astronaut lands on a newly-discovered planet (without an atmosphere). As an experiment, she throws vertically upwards a pure vanadium sphere of radius 2.0 cm and density 5.5 × 103 kg m3 with an initial speed of 3.0 ms 1. The point of release is 1.2 m above the ground. She observes the sphere to travel 4.8 m before it starts falling to the ground. Calculate the kinetic energy of the projectile just as it hits the ground.
A uniform solid bar with mass m and length L rotates with angular velocity ω about an axle at one end of the bar.What is the bar's kinetic energy?
The pulley system below consists of two masses connected by a string of negligible mass through a massless pulley. A spring with constant k is placed so that its equilibrium position is located a distance h below the bottom of mass m2. There is no friction either in the pulley, or between the surfaces of the masses and the platform. When the two masses m₁ and m2 are released from rest, mass m2 begins falling and pulls mass m₁ up the ramp. Find an expression for the maximum compression of the spring d caused by mass m2 when it hits the spring. Your answer should be in terms of the variables given (and g). m2 MW my 0

A 0.053 kg bullet is fired into a 5.38 kg wood block, which is attached to a pendulum. At the instant after they collide inelastically, the total mechanical energy of the system is 24.1 J. At the top of the swing of the pendulum, the block and bullet have risen to a maximum height, h, and now have a velocity of v = 0 m/s Use conservation of energy to find the maximum height, h, of the block + bullet system. Hint: The following formula will be useful PE = mx9.8×h %3D
You are working out on a rowing machine. Each time you pull the rowing bar (which simulates the oars) toward you, it moves a distance of 1.30 m in a time of 1.80 s. The readout on the display indicates that the average power you are producing is 88.0 W. What is the magnitude of the force that you exert on the handle?
