a ball is rolling ar 4.80m/s over level ground when it encounters a ramp which gives it an acceleration of -0.875m/s^{2. if the ramp is 0.750m long, what is the final velocity of the ball when it reaches the top of the ramp?

4.66m/s

Explanation:

Given parameters:

Initial velocity  = 4.8m/s

Acceleration = -0875m/s²

Length of the ramp  = 0.75m

Unknown:

Final velocity  = ?

Solution:

To solve this problem, we apply the right motion equation;

     V² = U²  +  2aS

V is the final velocity

U is the initial velocity

a is the acceleration

S is the distance  = length of ramp

   Insert the parameters;

      V²   = 4.8²  + 2(-0.875)0.75

      V²   = 23.04 - 1.31

      V²  = 21.73

      V = √21.73  = 4.66m/s

change tension

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
