Answer:
Explanation:
Net external force that exerted on the block is given as
here we know that
now we have
so we have
now the force exerted by bigger block on smaller block is given as
now we know that two blocks will exert equal and opposite force on each other
so here the force exerted by 2 kg block on 4 kg block will be
Answer:
0
Explanation:
Suppose this is for Excel. You can hide a row or a column by right-clicking on that row/column header and select row height or column width. After that simply input in 0 and click OK. The row or column will be hidden in the end, just like using a Hide command.
Answer:
the bigger the mass, the smaller the acceleration and the smaller speed
Explanation:
this can be proven from the formula F = ma
F = m×speed/time
Or a practical example is that of a heavy object and a light object if pushed with the same force, it'll be observed that the small object moves faster or with a greater speed than the heavy object
Answer:
c. Both mass of the bob and the length of the spring.

We know, momentum = mass * speed
25kgm/s = 2 kg * s
s = 25/2 = 12.5 m/s
