Q. An ideal spring with a stiffness of 379N/m is attached to a wall, and its other end is attached to a block that has a mass of 16-kg. The spring/block system is then stretched away from the spring's relaxed position until 59J of mechanical potential energy is stored in teh spring. Then the system is released to oscillate freely, with block sliding horizontally on the level, frictionless floor. Find out the speed of the block when the spring is compressed by 13.40 cm.
The pilot of an aircraft wishes to fly due west in a 49.8 km/h wind blowing toward the south. The speed of the aircraft in the absence of a wind is 192 km/h.
A capacitor (capacitance C1) is connected across the terminals of an ac generator. Without changing the voltage or frequency of the generator, a second capacitor (capacitance C2) is added in series with the first one.
Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.40 s before coming to rest. How numerous revolutions did the centrifuge complete after being turned off.
An old hunting weapon was a rock on the end of a string. The hunter would swing the rock in horzontal circles and then throw it. If the rock had a mass of 2 kg and the 2 m long string breaks when the tension is 60N.
A hunter aims directly at a target (on the same level) 101m away. If the bullet leaves the gun at a velocity of 203m/s, by how much will it miss the target.
A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision. If they skid for 5.4 seconds before stopping, how far did they skid?
A 21g particle is moving to the left at 29 m/s. How much work must be done on the particle to cause it to move to the right at 41 m/s.
