1.	A train starting from rest attains a velocity of 20m/s in 2 minutes. assuming that the acceleration is uniform, find1 the acceleration 2 distance travelled by the train, while it attained this velocity.3 what do you understand by mass of body4 is mass a scalar or vector state its si unit 5 how does the mass of body change whent it is taken into deep space
Answer» Answer: 1) a= v-u/t a= 20-0/120sec 1.667m/s^2 2) d=s×t d= 20×120= 2400m 3) Mass is a dimensionless quantity REPRESENTS AMOUNT of MATTER in a partical. 4) Mass is SCALAR quantity.

Answer»

Answer:

1) a= v-u/t

a= 20-0/120sec

1.667m/s^2

2) d=s×t

d= 20×120= 2400m

3) Mass is a dimensionless quantity REPRESENTS AMOUNT of MATTER in a partical.

4) Mass is SCALAR quantity.
