Question: A projectile is fired with speed (V0) at an angle theta) from the horizontal as shown in the figure . Part B: What is the range of the projectile? Express the range in terms of (V0, theta, or g) Part C: Find th ...
You throw two balls of equal masses ( m =0.992 kg) vertically upward at an interval of Δ t = 1.41 seconds with the same initial speed of v i=35.3 m/s from the same height. At what height will they collide, measured rel ...
Near the Earth's surface, a compact car of total mass M is driven on a large, revolving, horizontal, disk-shaped platform which itself rotates about its center at a fixed angular frequency ω. At t = 0, the driver leaves ...

Question: A solid disk of mass m1 = 9.6 kg and radius R = 0.24 m is rotating with a constant angular velocity of ? = 30 rad/s. A thin rectangular rod with mass m2 = 3.4 kg and length L = 2R = 0.48 m begins at rest above ...
Question: In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80 m/s2 . Ignore air resistance. How long is the flea in the air from the time it jump ...
In an attempt to skip a rock off the surface of a lake, you throw the rock from a height h=1.67 m above the lake surface with an initial speed of v0 = 6.85 m/s at an angle of θ=12.3° below the horizontal. How long until ...
Question: Seat belts and air bags save lives by reducing the forces exerted on the driver and passengers in an automobile collision. Cars are designed with a "crumple zone" in the front of the car. In the event of an imp ...
Question: In short-track speed skating, the track has straight sections and semicircles 16 m in diameter. Assume that a 64kg \;kg skater goes around the turn at a constant 11m/s Part A: What is the horizontal force on th ...
Question: You're driving down the highway late one night at 20m/s when a deer steps onto the road 35m in front of you. Your reaction time before stepping on the brakes is 0.50s, and the maximum deceleration of your car i ...
