Complete Question

The diagram for this question is shown on the first uploaded image

Answer:

x  =  4.70  \  m     ,   y =  0.2803 \  m

Explanation:

From the question we are told that

     The initial velocity of the arcade ball is  u  =  7.0 \  m/s

     The time taken by the ball to enter the basket is  t =  0.95 \ s

Generally the x -component of the initial  velocity is  

            u_x  =  7 *  cos (45)    

=>         u_x  =  4.95 \  m/s

Generally the y -component of the initial  velocity is  

            u_x  =  7 *  sin(45)    

=>         u_y  =  4.95 \  m/s

  Generally the distance x is mathematically represented as

                 x  =  u_x  *  t

=>              x  =  4.95 *  0.95      

=>              x  =  4.70  \  m    

Generally from kinematic equation the distance y is mathematically represented as

               y =  u_y * t  - \frac{1}{2} *  g * t^2

=>            y = 4.95 * 0.95  - \frac{1}{2} *  9.8 * 0.95^2

=>            y =  0.2803 \  m
