What else can I help you with?
Can you have velocity without acceleration?
Yes, a body can have aceleration without velocity. Consider sin x the position; cos x is the velocity and -sin x is the acceleration. Here the acceleration negative when x=90 degrees and the velocity is zero at 90 degrees.
A boy is tobogganing down a smooth slope inclined at 20 degrees to horizontal find his acceleration assuming resistances can be neglected?
The acceleration of the boy can be found using the equation a = g * sin(θ), where g is the acceleration due to gravity (approximately 9.81 m/s^2) and θ is the angle of the slope (20 degrees). Therefore, the acceleration of the boy would be a = 9.81 m/s^2 * sin(20 degrees) ≈ 3.36 m/s^2.
A football is kicked with a velocity of 31 ms at an angle of 41 degrees what is the balls acceleration in the vertical direction?
The acceleration in the vertical direction is due to gravity and is approximately 9.8 m/s^2 downward. The vertical acceleration remains constant throughout the ball's flight trajectory.
Does the degree of a curve effect acceleration?
Yes, the degree of a curve can affect acceleration. In a curve with a higher degree, the change in direction is sharper, which can lead to higher acceleration as the vehicle needs to adjust its speed to navigate the curve effectively. In contrast, curves with lower degrees may require less acceleration due to their more gradual changes in direction.
Why is the acceleration vector is always at 90 degrees to the velocity vector?
That's only true when the object is in circular motion.The circular motion is the result of a force (which produces acceleration)that's always perpendicular to the object's velocity.Like the gravitational force between the Earth and a geostationary satellite,or the tension in the string of a yo-yo that's doing circles.
How many degrees is it when a tornado is happening in Topeka?
it matters where it is
Discuss the validity of extrapolating the acceleration value to an angle of 90?
Extrapolate the experimental values of acceleration, vs. angle of the incline, to find the acceleration when the angle of inclination = 90 degrees. The acceleration at 90 degrees will equal 9.81 m/s/s, since this is the free-fall acceleration.
How hot is a tornado?
Tornadoes can be very hot, with air temperatures inside reaching up to 2,000 degrees Fahrenheit (1,093 degrees Celsius). This extreme heat is due to the high wind speeds and friction within the tornado vortex.
What is the temparature when there is a tornado?
There is no limit to what the temperature could be; It can be zero degrees or it could be a hundred. However the average temperature is 58 degrees.
Do tornado air masses form north of 50 degrees north latitude or south of 50 degrees south latitude?
There is no such thing as a "tornado air mass" but tornadoes can occur north of 50 degrees. Tornadoes have been recorded in northern Europe, including the UK and Scandinavia.
How warm is it inside a tornado?
That is not known. Not enough measurements have been taken from inside a tornado.
What is the temperature during a tornado?
The typical temperature during a tornado can vary, depending on the temperature of the air inside the tornado. There have been temperatures recorded as low as 50 degrees and as high as 103 degrees.
A child slides down a frictionless slope at 25 degrees to the horizontal Calculate the child's acceleration down the slope?
a(child acceleration)=g(gravitational acceleration)*sin25=4.144 m/s2
What is the exact location of the joplin tornado?
The Joplin tornado struck the southern side of the city of Joplin, Missouri and some of the surrounding countryside, which is in the southwestern corner of the state. The tornado traveled 22 miles (7 miles inside the city). It started at 37.05 degrees north, 94.59 degrees west, about a mile west of Joplin. The tornado dissipated at 36.98 north, 94.22 west, about 14 miles southeast of the city.
Can you have velocity without acceleration?
Yes, a body can have aceleration without velocity. Consider sin x the position; cos x is the velocity and -sin x is the acceleration. Here the acceleration negative when x=90 degrees and the velocity is zero at 90 degrees.

What happens when a tornado hits?
When a tornado hits, it can cause significant damage by lifting and destroying structures, vehicles, and trees in its path. Tornadoes can also create strong winds that can cause injuries and fatalities. It is important to take shelter in a sturdy building or underground if a tornado warning is issued.
