A ball is thrown upward from the ground with a speed of 36.0 ms At what time after being thrown does the ball have a velocity of zero?
A ball that isn't being held up by anything will accelerate vertically because of the influence of gravity. It's rate of acceleration will be 9.78 meters per second2, directed downward, meaning that each second, its speed in the downward direction will be 9.78 meters per second faster than it was 1 second earlier. When this particular ball is released, its downward speed is negative 36 meters per second. How many times (seconds) does gravity need to increase its downward speed by 9.78 m/s in order to increase its downward speed to zero ? (36 / 9.78) = 3.681 seconds (rounded). That's when the negative downward speed has increased to zero, and becomes a positive downward speed. So it's also the peak of the toss.
What are the units for average velocity?
The S.I unit for velocity is meters per second (m s-1).
What is the metric unit for velocity?
Metre per second, ms-1.Although kilometres per hour is used for things like cars and aeroplanes.
Explain the term angular velocity?
Angular velocity is a measure of how fast something is spinning. It can be measured as either degrees per second or radians per second. 1 turn per second would be 2 PI radians per second or 6.283185... rad/sec or 360o /sec
What is dimension of angular velocity?
[ T-1 ] . Reciprocal time, from "degrees per second" .The angle part of it is dimensionless.
What is a skydivers downwords velocity after 1 second when falling from a hovering helicopter?
Neglecting air resistance his velocity after 1 second will be 9.81 m/sec or 32.2 ft/sec.
What is the skydiver's upward velocity after 1 second?
I presume you mean 1 second after jumping from the plane. Since skydiver's fall, their velocity is generally in a downward direction, so the upward velocity is negative. The formula v = gt, where g is the acceleration due to gravity which is about 32.2 feet per second per second, tells us that after 1 second it would be about -32.2 feet per second.
How does velocity varies with the vertical distance traveled by the object?
When an object falls vertically downward, its velocity increases according to the following equation:2aS=vf2 - vi2 or ,2*10*S=v2, orv=(20S)1/2.There is a second case in which a body is thrown vertically upward, here its velocity decreases as it moves upward. Here its velocity becomes zero as it reaches the highest point

A banana is thrown straight out so it has both horizontal and vertical velocity After 1 second, what is its vertical velocity?
9.8
How can velocity be expressed in units?
metres per second ms-1
When a ball is thrown vertically upward at initial velocity of 15 meter per second Find the position and velocity after 1.0 second and 40 second after leaving your hand?
1 sec : position = 10.1 metres above your hand, velocity = 5.2 ms^-1.40 sec : position = 7240 metres below your hand, velocity = 377 ms^-1 downwards.
What is the unit of velocity in SI unit system?
meter/second or ms-1
An angry construction worker throws his wrench downward from a height of 128 feet with an initial velocity of 32 feet per second. The height of the wrench above the ground after 1 second is what?
s=u*t +1/2*a*t*t u=32 t=1 a=33 s=48.5 hence height above ground=128-48.5 =79.5 feet
What is the unit for measuring acceleration?
1 metre per second velocity increase, every second. > 1 (m/s) / s
What unit is used to express velocity?
meter's per second[ms-1]
