1. A roach that runs for its life because you try to hit it with your physics book runs off the horizontal tabletop with a speed of 0.578 m/s. It strikes the floor a horizontal distance 0.376 m away from the edge of the table. Ignore air resistance.
Find the height of the table?
2. A roach that runs for its life because you try to hit it with your physics book runs off the horizontal tabletop with a speed of 0.634 m/s. It strikes the floor a horizontal distance 0.261 m away from the edge of the table. Ignore air resistance.
What will be the horizontal component of the roach's velocity just before it hits the floor?
What will be the vertical component of the roach's velocity just before it hits the floor?
Two carts with masses of 10.60 kg and 2.50 kg, respectively, move in opposite directions on a frictionless horizontal track with speeds of 6.70 m/s and 3.50 m/s, in that order. The carts stick together after colliding head-on. Find the final speed of..
Two resistors have resistances R(smaller) and R(larger), where R(smaller)
Two simple pendulums have length of 81-cm and 64-cm they are released from the same angular position at the same instant. After how much time would they both arrive at their initial position simultaneously.
What is the magnitude of the vertical component of its velocity as it strikes the ground.
What is an amplitude at a point where two pulses are crossing if the end at which reflection occurs is free to slide up and down.
Find the shear strain that results if a force of magnitude 8×10^5 is applied to the top square face of the plate, parallel to the side, and a force of equal magnitude is applied in the opposite direction to bottom face of the plate.
A bullet is fired at an angle of 60o with an initial velocity of 200.0 m/s. Explain how long is the bullet in the air? What is the maximum height reached by the bullet?
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
