Q. A mountain climber jumps a 3.2 m-wide crevasse by leaping horizontally with a speed of 7.1 m/s. If the climber's direction of motion on landing is -45^circ, what is the height difference between the two sides of the crevasse?
Q. A major-league catcher gloves a 85 mi/h pitch and brings it to rest in 0.17 m. If the force exerted by the catcher is 803 N, what is the mass of the ball?
Heat is extracted from a certain quantity of steam at 100 degrees celsius. Thus the steam changes into ice at 0 degrees celsius. If this energy were used to accelerate the ice from rest, what would be the linear speed of the ice.
Calculate for the capacitance, the charge of plate, and magnitude of electric field between the plates for a capacitor whose plates are 11 mm apart are 2.00 m-2 in area and being connected to a source with potential difference of 270V.
Expand Lagrangian to second order about equilibrium coordinates, r_0, phi = wt and find the condition for stability against small oscillations.
Two meteoroids are heading for earth. Their speed as they cross the moon's orbit is 2.3 km/s. The second meteoroid misses for earth by 2680 km. What is its speed at its closest point.
The average force exerted on him by the ground is +18000 N, where the upward direction is taken to be the positive direction. From what height did the student fall? assume that the only force acting during the collision is that due to the ground.
The loaded cab of an elevator has a mass of 3.6 x 10^3 kg and moves 193m up the shaft in 20s at constant speed. At what average rate does the force from the cable do work on the cab.
