An air hockey puck is attached to a string with a length of .45 m and is set in a circular motion with a period of 2.0 s. If the tension in the string is .789 N and we assume there is no friction:
A. What is the tangential speed of the puck?
B. What is the centripetal acceleration of the puck?
C. What is the mass of the new puck?
D. What would be the new tension in the string if the tangential speed was twice as fast?
Objective questions based on work, energy, power.
A bartender slides a beer mug at 1.30 m/s towards a customer at the end of a frictionless bar that is 2.0m tall. The customer makes a grab for the mug and misses, and the mug sails off the end of the bar.
A projectile is fired at v0 = 407.0 m/s at an angle of ? = 72.0o with respect to the horizontal. Assume that air friction will shorten the range by 34.1%. How far will the projectile travel in the horizontal direction, R?
what was the initial speed given to the rock. A light plane is headed due south with the speed of 154 km/h relative to still air. After 1.06 hour, the pilot notices that they have covered only 127km and their direction is not south but southeast (4..
Your plane reaches its takeoff runway and then holds for 5.0 min because of air-traffic congestion. What is its takeoff speed
As a particle moves from the origin to (1i + 7j) m, it is acted upon by a force given by (2i + 6j) N. Calculate the work done by this force on the particle
