Q. The speed of sound in air is 332 m/s at 0°C. It increased 0.60 m/s for each degree above zero. Calculate the speed of sound at the temperature of the room.
Q. On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 3.3 times as far as he would have on earth, given the same initial velocities on both planets. The ball is launched at a speed of 53 m/s at an angle of 50° above the horizontal. When the ball lands, it is at the same level as the tee.
(a) On the distant planet, what is the maximum height of the ball?(b) On the distant planet, what is the range of the ball?
In a certain RL time constant circuit, it takes 135 msec for the current to reach maximum after the switch is closed.
At what angle have to the laser beam in the diagram be aimed at mirrored ceiling in order to hit the midpoint of the far wall? The length of the room is a=4.9 m and its height is b=3.00 m.
The altitude of a hang glider is increasing at a rate of 6.80 m/s. At the same time, the shadow of the glider moves along the ground at a speed of 15.5 m/s when the sun is directly overhead. Calculate the magnitude of the glider’s velocity.
A stunt pilot performs a circular dive of radius 715m. At the bottom of the dive pilot has a speed of 265 m/s which at that instant is increasing at a rate of 15 m/s2(along the direction of vector B) What total acceleration does the pilot have at ..
Vector A has a magnitude of 9.10 units and makes an angle of 54.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods find the following.
What is the instantaneous power, at a time of 0.00700 seconds, dissipated by a 200 ohm resistor in a resonant AC circuit powered by a generator with a 21.0 V highest potential difference operating at 5000 rad/s .
A 60 kg skier starts from rest at a height of H = 21 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. avoid the effects of air resistance and assume the ramp is frictionles..
The bucket is released from rest at the top of a well and falls a distance 10.3 to the water. You can ignore the weight of the rope.
Find the change in internal energy using first law of thermodynamics.
A 9.05 kg projectile is fired vertically upward. Air drag decreases the mechanical energy of the projectile-Earth system by 77.5 kJ throughout the projectile's ascent. How much higher would the projectile have gone were air drag negligible.
A typical Major League fastball is thrown at about 99 mph and with a spin rate of 103 rpm. If the distance between the pitcher's point of release and the catcher's glove is exactly 65.5 ft, how many full turns does the ball make between release and c..
A roller coaster is towed up an incline at a steady speed of 0.51m/s by a chain parallel to the surface of the incline. The slope is 2.85 % that means that the elevation increases by 2.85 m for every 100m of horizontal distance.
