How long it takes for a ball to roll down a ramp?
The time it takes for a ball to roll down a ramp will depend on the angle of the ramp, the friction between the ball and the ramp, and the initial velocity of the ball. However, in ideal conditions with no friction and starting from rest, the time can be calculated using physics equations for motion.
What keeps a ball moving downhill?
The force of gravity pulls the ball downhill, causing it to accelerate as it moves. As long as there is a slope for it to roll on, the ball will continue moving downhill until it reaches a flat surface or encounters a force that slows it down.
If you throw a ball straight upward at a speed of 20 meters per second how long will it take to reach zero speed?
The ball will reach zero speed at the peak of its trajectory after approximately 2 seconds. This is because the acceleration due to gravity will gradually slow down the ball until it stops momentarily before falling back down.
What are the methods of the long jump?
The two main methods of the long jump are the hang technique and the hitch-kick technique. In the hang technique, the jumper takes off and extends their legs forward before bringing them down in front. In the hitch-kick technique, the jumper drives their knee up, kicks their legs in a cycling motion, and then extends them before landing.
Calculate the hang time of an athlete who jumps a vertical distance of 0.75 meter?
What is the "hang time" of an athlete who can jump a vertical distance of 0.75 m? The athlete goes up 0.75 m, and then comes back down the same distance. Going up and coming down take the same time, so the hang time is twice the time for the athlete to fall 0.75 m from rest. How long is that? d = 0.75 m, a = 10 m/s2, t = ? The hang time is twice the time to fall = 2(0.385 s) = 0.77 s Check: http://www.batesville.k12.in.us/physics/phynet/mechanics/kinematics/answers/answers_sep_30.htm Hope you understand

How long can a bat hang upside down?
Bats can hang upside down for as long as they want. They do not need to use any muscles to hold on to something. They have special tendons in their feet that lets them hang around without exerting any energy. All they have to do to hang is relax. The weight of the upper body pulls down on this tendon and causes the talons to clench or grab hold. The talon joints lock and the bats weight keeps them closed. The bat only needs to release its grip to fly off.
