How long in seconds does it take to hit the ground after a ball is dropped from a height of h70 m?
neglecting air resistance, distance = 1/2 gt^2 where g = acceleration of gravity = 9./8 m/sec/sec 70 = 1/2 (9.8) t^2 14.28 = t^2 t = square root 14.28 = 3.78 seconds
What is the kinetic energy of a 3- kilogram ball that is rolling at 2 meters per second?
1
During play a ball with a diameter of 3.00 inches splits exactly in half What is the volume of each portion of the ball?
7.07
What is rest position or equilibrium position?
Rest position or equilibrium position occurs when all the forces (gravity, the wind, friction etc) exerted on an object are equal.For example, a rolling ball is not in equilibrium because one or more forces (gravity or the force you used to initially move the ball) are greater in strength than the friction (both between the ball and the surface it is rolling on and between the ball and the air).The ball will stop rolling when the force causing it to move 'forwards' is overcome by frictional force. The ball will then be in equilibrium, or at rest.
Out of 9 balls 8 balls weight the same 1 is lighter. using scales twice which ball is lighter?
Set three balls aside. Divide the remaining 6 balls into 2 groups of 3 and weigh them. If the groups weigh the same, the lightest ball must be in the group you set aside. Otherwise, the lightest ball is in the group that weighed less. Take the group of thee that remains and set aside one ball. Weigh the other two. If the two balls weigh the same, the lightest ball must be the one you set aside. Otherwise, the lightest ball is the one that weighed less.
After 2 seconds its velocity is 9 meters per second what is the accleration of a ball?
If the ball started off stationary and the acceleration is the same for the 2 seconds, then the acceleration of the ball is:Speed / time = acceleration9 (m/s) / 2 (s) = 4.5 (m/s/s)Hope this helps.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 5 seconds?
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.
You throw a ball straight up with a velocity of 40 meters per second What is the ball's velocity after 5 seconds?
it is 10 meters per second straight down
When it is doubled it is a fuzzy ball?
Pom. Pom.
If an opponent is guarding you for 5 seconds but you are still advance the ball is this a 5 second call?
Yes..You must separate or pass the ball.
What is the velocity of a ball in meters per second that drops from a roof and the speed was at 3.03 seconds?
If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
What is the average speed if a ball goes 24 meters in 0.5 seconds?
48 metres per second.
What is a 10 second violation?
Also know as Backcourt Voilation, it is when a player or the ball does not pass the halfcourt line in ten seconds. If the line is not passed in the ten seconds, it results in a turnover and the other team gets the ball.
A ball rolls qat 3 meters per second how much time does it take the ball to roll 6 meters?
At 3 metres per second it will roll 6 metres in 2 seconds.
A ball is in free fall after being dropped what will the speed of the ball after 2 seconds of free fall?
The speed of an object in free fall increases by 9.8 m/s every second. Therefore, after 2 seconds of free fall, the speed of the ball will be 9.8 m/s * 2 seconds = 19.6 m/s.
If a soccer ball is hit at 21 miles per hour then what is the balls speed in meters per seconds?
The ball's speed is 9.4 meters per second.
