Step-by-step explanation:
Let say price of one book is X, and price of one pen is Y.
2X+3Y =225
3x+4Y= 320
By multiplying 3 in equation 1 and multiplying 2 in equation 2
6X+9Y =675
6X +8Y = 640
So by elimination method Y is equal to 35.
The cost the cost of one pen is 35 rupees.

F = ma
a = F/m
a = 5 N / 10 kg = 0.2 m/s²
S = ut + at²/2
8 m = 4u + 4*4²/2
8 = 4u + 32
4u = 24
u = 6
