- e.g. A wood block mB is static on smooth table with another block MA on one ends of it. Now give m an initial velocity vo to make it sliding on B. assume the friction coefficient is μ, m₁=m³, and when A arrives at the other end of B, they have the same speed. What is the length of B and the displacement of B (A is a mass point).. Execute A A gives B a friction um g and B gives A a friction -µmäg.

- SCSU physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" have not been made public, there have been rumors of the drop took 2.20 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You may assume final position to be zero.arrow_forwardA yacht is cruising at a speed of 10.4 m/s in still water when it shuts off its engines and coasts to rest. The water exerts drag forces on the yacht such that its speed during -ct v,e, where v is the speed at time t, v 0, and c is a constant. At a time of t = 17.5 s after the engines are cut, the speed is is the initial speed at t coasting is given by v 5.00 m/s. What is the constant c (in s) in the expression?

- You are visiting your cousins for Christmas in New Hampshire where it is freezing. They are crazy. They get the idea to spray water on the roof so it will become very slippery enabling you all to slide off of it in a sled (metal box). The frozen water on the roof has essentially removed all friction. If the angle of the roof is 20 degrees with respect to the horizontal, and (starting from rest) you slide for a distance of 5 meters before reaching the edge, and if the edge of the roof is 6 meters above the ground, how far from the edge will you travel in the x direction before you hit the ground? g = 9.8 m/s?arrow_forwardA plane is initially at rest on the ground. The minimum speed for the plane to take off is 50 meters/sec and the runway is 2 km long. What should be the minimum acceleration of the plane so that it has a successful take off?arrow_forwardA toad with mass of 280 g leaps into the air to catch a fly.

- 1.You are in a plane that flies horizontally with speed 900 km/h (250 m/s) when an engine falls off. Neglecting air drag, assume it takes 25 seconds for the engine to hit the ground. (a) How high was the plane flying? (b) What is the horizontal distance that the engine covers before hitting the ground? (c) If the plane somehow continuous to fly as if nothing had happened, where is the engine relative to the airplane at the moment the engine hits the ground?arrow_forwardYou are standing at the top of a cliff that has a stairstep configuration. There is a vertical drop of 6 m at your feet, then a horizontal shelf of 5 m , then another drop of 4 m to the bottom of the canyon, which has a horizontal floor. You kick a 0.44 kg rock, giving it an initial horizontal velocity that barely clears the shelf below What initial horizontal velocity v will be required to barely clear the edge of the shelf below you? The acceleration of gravity is 9.8 m/s^2 . Consider air friction to be negligible. Answer in units of m/s. How far from the bottom of the second cliff will the projectile land? Answer in units of m.arrow_forwardYou are standing on your balcony in an apartment building. You tossed a coin straight upwards at 4 m/s.
