Answer:
Force exerted by the lighter block on the heavier block is 6.63 N
Explanation:
Given Data
F = 80N
m = 1kg
M = 11kg
Solution:
*We assume that there is no friction
Calculating the acceleration of the system
a =
a =
a =
a = 6.67m
Let's write the Equation of Motion of the heavier block
= F -
Ma = F -
force exerted by the lighter block on the heavier block is calculated as
= F - Ma
= 80 - (11 x 6.67)
= 6.63 N
