dmitriy555 [2]

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

Why current remains same in series combination of resistors in all resistors and p.d. remains different?
IgorC [24]
Current at all points of a series circuit must be the same, because there's no place in the circuit where electrons are being manufactured, and no place where they're leaking out and falling on the floor. The nimber of electrons that leaves the loop is the same number that entered it. I'm not sure what is nmeant by "p.d. remains different" .
