You drop a ball from a cliff it lands 4 seconds later what is the balls average speed during the 1st second it is in free fall?
The basic equation for average velocity is distance over time. However, if the velocity is changing uniformly, as it is in free fall, you can use initial velocity plus final velocity divided by two. That makes this problem easy. In free fall the object accelerates at 9.8 m/ss. That means every second it picks up 9.8 m/s of speed. So if is dropped from rest, then one second later its speed will be 9.8 m/s. Its average speed during that time is then initial velocity = 0 plus final velocity = 9.8 divided by 2, to get ; 4.9 m/s.

Why do glass balls bounce higher than rubber balls?
Glass balls tend to bounce higher than rubber balls due to their density and hardness. Glass balls have less energy loss upon impact because they are rigid and less deformable compared to rubber balls. This allows glass balls to retain more of their original kinetic energy during the bounce, resulting in a higher bounce height.
Do dryer balls effectively prevent static cling in laundry?
Yes, dryer balls can effectively prevent static cling in laundry by reducing friction and helping to separate clothes during the drying process.
What happens to all the momentum when two billiard balls collide.?
In a collision between two billiard balls, momentum is conserved. This means that the total momentum of the two balls before the collision is equal to the total momentum after the collision. The momentum is transferred between the two balls during the collision, resulting in changes in their individual velocities.
