Q1. A 15.0 m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes a 60.0 angle with the horizontal. (a) Find out the horizontal and vertical forces the ground exerts on the base of the ladder when an 800 N fire-fighter is 4.00m from the bottom. (b) If the ladder is just on the verge of slipping while the fire-fighter is 9.00m up, what is the coefficient of static friction between ladder and ground?
Q2. A Texas cockroach of mass 0.232 kg runs counter clockwise around the rim of a lazy Susan (a circular disk mounted on a vertical axle) that has a radius 10.70 cm, rotational inertia 4.37 x 10-3 kg•m2, and frictionless bearings. The cockroach's speed (relative to the ground) is 3.00 m/s, and lazy Susan turns clockwise with angular velocity ω0 = 3.03 rad/s. The cockroach finds a bread crumb on the rim and, of course, stops. What is the angular speed of the lazy Susan after the cockroach stops?
A mass m = 90 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 18.8 m and finally the flat straight section at the same height as the center of the loop (18.8 m off the ground). Because the mass would not..
Determine the simple harmonic motion of the spring what ac velocity is ball moving
A meterstick is at rest in an inertial frame S2. If S2 moves with a speed of 0.7c with respect to a rest frame S1, find the length of the meterstick as measured in frame S1 according to classical physics. Reply in units of m.
A car dealer claims that his product will accelerate at a constant rate from rest to a speed of 200 km/hr in 8s. What estimated distance will the car travel.
A 9.0 cm diameter wire coil is at first oriented so that its plane is perpendicular to a magnetic field of 0.67 T pointing up. During the course of 0.30 s, the field is changed to one of 0.25 T pointing down. What is the average induced emf in coil.
A pitcher throws a fastball horizontally at a speed of 150 km/h toward home plate, 18.4m away. If the batters combined reaction and swing times total 0.37s, how long can batter watch the ball after it has left the pitcher's hand before swinging? In t..

A 500 turn solenoid with a length of 20 cm and a radius of 3.0 cm carries a current of 3.0 A. A second coil of four turns is wrapped tightly about this solenoid so that it can be considered to have the same radius as the solenoid. Find when the curre..
An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.
When the plunger is pushed, contents of the syringe are forced throughout a hollow needle (also of circular cross-If a 4.0 N force is applied to plunger and diameters of the plunger and the needle are 1.20 cm and 2.50 mm, correspondingly, what force ..
