7. If the impact of the golf club on the ball in the previous question occurs over a time of 2 x 10 seconds, what force does the ball experience to accelerate from rest to 73 m/s?

3.65 x mass

Explanation:

Given parameters:

Time  = 20s

Initial velocity  = 0m/s

Final velocity  = 73m/s

Unknown:

Force the ball experience  = ?

Solution:

To solve this problem, we apply the equation from newton's second law of motion:

    F  =  m  

m is the mass

v is the final velocity

u is the initial velocity

 t is the time taken

So;

  F  = m ( )  = 3.65 x mass

more than, less

less than, more

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
