What else can I help you with?
A ball is dropped from a window and takes 2 seconds to reach the ground. It starts from rest and reaches a final speed of 20 MS What is the balls acceleration?
The acceleration of the ball can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the initial velocity is 0 m/s, the final velocity is 20 m/s, and the time is 2 seconds. Therefore, the acceleration would be (20 m/s - 0 m/s) / 2 s = 10 m/s^2.
Does a ball dropped with horizontal velocity take longer to hit the ground than on dropped at rest?
No, both balls will hit the ground at the same time, assuming they are dropped from the same height and in a vacuum. The horizontal velocity does not affect the time it takes for an object to fall vertically due to gravity.
What materials would you need to measure the amount of kinetic energy two balls would have id dropped from a greater height?
To measure the amount of kinetic energy, you would need a measuring tape or ruler to determine the height from which the balls are dropped, a timer to measure the time taken for the balls to reach the ground, and a scale to measure the mass of the balls. The kinetic energy can be calculated using the formula KE = 0.5 * m * v^2, where m is the mass of the ball and v is the velocity it reaches upon impact.
Will a ball drop from rest reach the ground guicker than the one launched from the same height but with an initial horizontal velocity?
If we can ignore the effects of air resistance and consider gravity only, then thehorizontal component of velocity has no effect on the vertical component.These balls accelerate vertically at the same rate, and hit the ground at the same time.In an extreme case, the same is true of a shot fired from a gun and one dropped fromthe muzzle at the same time.
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.
Which ball if dropped has more velocity a bouncy ball or a tennis ball?
This is an old experiment. Neither. Both balls have the same velocity as gravity draws on them equally.
