when sled just start to move the force on the sled will be equal to the static friction
So here we need to find the value of static friction
We know that
m = 30 kg
now we know that normal force on the block is counterbalanced by weight of the block
now in order to find the friction force we can use
so it requires 59 N of force to move the sled
Answer:
11.3 g
Explanation:
given,
density of the lead = 11.3 g/cm³
volume = 1 cm³
mass of the lead = ?
we know,
mass = volume x density
mass = 1 x 11.3
mass = 11.3 g
hence, the mass of the lead is equal to 11.3 g
