Answer:
the net work done on the cart is 160 J.
Explanation:
Given;
mass of the cart, m = 5.0 kg
initial velocity of the cart, u = 6 m/s
final velocity of the cart, v = 10 m/s
The net work done on the cart is equal to change in average kinetic energy of the cart;

Therefore, the net work done on the cart is 160 J.
Answer:
Explanation: V = 3 cm/s = 0.03 m/s
BY THE FORmULA OF K.E
K.E = 1/2 mV^2
300 =1/2 m (0.03)^2
m = 300 x 2/0.0009
m= 666666.66kg
Answer:
c. because A will land first becuase its heavier
and D.
Explanation:
There are several information's of immense importance already given in the question. The answer to the question can be easily determined using those available information's.
Mr of pure tungsten = 183.84
Mass of tungsten = Mole * Mr
= 0.7 * 183.84
= 128.7 gm
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option or the penultimate option.
Answer:I think that is false
