Actually Welcome to the Concept of the Kinematics in real world.
So, as given here, we have to find the Mass of the bus from the given momentum, so we get as,
P = m * V
momentum = mass * velocity
here, P= 152625 kgm/s and v= 11.1 m/s
so substituting we get as,
m = 152625 ÷ 11.1 => 13,750 kg
hence,the mass of the bus is 13,750 kg.
Answer:
So scale will read a force force of 880 N
Explanation:
We have given that mass of the person m = 80 kg
Force of gravity from the earth F = 800 N
We know that force is given by 
So 

It is given that acceleration of the elevator a = 
We have to find the force which scale read
So force is given by 
So scale will read a force force of 880 N
P is disproportional to t, which means that if P increases with x factor, the t will decrease with the same x factor. If t increases then P decreases
25x = 200*30
25x= 6000
x= 240
Answer:
The beaker holds 277.2 mL
Explanation:
Empty weight of beaker = 40.25 g
Weight of beaker with water = 317.45 g
Weight of water = 317.45 - 40.25 = 277.2 g
Density of water = 1 g/mL
We have
Mass = Volume x density
277.2 = Volume x 1
Volume = 277.2 mL
The beaker holds 277.2 mL
