Question

the block of known mass is placed in front of trolley as shown in figure when a known mass is kept on pan the block get displaceda) where does block get energy from
b if mass on pan is increased will work done will be more.
c what type of energy possessed by the trolley ​

Answer 1

a) Trolley

b) Yes

c) Kinetic energy

Explanation:

a) The block gets the energy from the trolley.

b) Yes, if the mass on the pan is increased then there will be more work done.

c) The trolley possess Kinetic energy.

Answer 2

Answer:

a) From trolley, b) Yes, c) Kinetic energy.

Explanation:

a) where does block get energy from:

• The block gets energy because work is done on it by the moving.
• The pan makes the block move by the trolley.

b) If mass on pan is increased will work done will be more:

• Yes more work will be done on the block as trolley moves faster.

c) What type of energy possessed by the trolley ​:
