Q. Your cup of coffee is too hot to drink when served at 95.What is the mass of an ice cube, taken from a -19.0 freezer, that will cool your coffee to a pleasant 62.0?
Q. The press box at a baseball park is 31.0 ft above the ground. A reporter in the press box looks at an angle of 20.0 degree below the horizontal to see second base. What is the horizontal distance from the press box to second base?
Describe briefly a current health problem. A father racing his son has half the kinetic energy of the son, who has one-third the mass of the father. The father speeds up by 2.5 m/s and then has the same kinetic energy as the son.
How many revolutions does the ball make during its fall. Now assume that the ramp is frictionless, so that the ball slides instead of rolling. Through what horizontal distance d does the ball move before landing in this case.
The object is authorized to move on a horizontal frictionless surface. The object is released from rest when the spring is compressed 0.15 m. Find out the force on the object.
A 2.65 block is pushed 1.69m up a vertical wall with a constant speed by a constant force of magnitude F applied at angle 55.4 degrees with the horizontal. g= 9.8 m/s2. If the coefficient of kinetic friction between the block & wall is 0.54, Calcu..
Find out the acceleration of the crate if the applied force is 380 , the mass of the crate is 32 and the coefficient of kinetic friction is 0.42.
An 8,000 rocket is shot straight up from the Earth's surface with the initial speed of 800 m/s. How high does it go.
The gravitational force exerted on a baseball is 2.23 N down. A pitcher throws the ball horizontally with velocity 14.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 169 ms. The ball starts from rest.
Find out the change in entropy of the system
A driver in a car travelling at the speed of 78 km/h sees a cat km away on the road. How long will it take for the car to accelerate uniformly to a stop in exactly 99 m.
A chair of weight 125 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 35.0 N directed at an angle of 42.0 below the horizontal and the chair slides along the floor. Using Newton's laws, compute..
A spherical mirror is polished on both sides. When the convex side is used as a mirror, the magnification is +1/4. What is the magnification when the concave side is used as the mirror, the object remaining the same distance from the mirror.
A ranger in a national park is driving at 28.0 mi/h when a deer jumps into the road 225 ft ahead of the vehicle. After a reaction time t, the ranger applies the brakes to produce an acceleration of a = -9.00 ft/s2. What is the most reaction time a..
