Question

which would require a greater force accelerating a 2kg mass at 10 meter per second square or a 7kg mass at 5 meter per second square​

Answer 1

Answer:

7kg body will require greater force.

Explanation:

2X10=30N

7X5=35N

Answer 2

Explanation:

force =Mass ×acceleration

F1=m1×a1

F1=2kg×10m/s²=20kgm/s²

means 20Newton

20 N

F2=m2×a2

F2=7kg×5m/s²(here we multiply numerical value with numerical value and unit with unit)

we know that 1kgm/s²=1Newton

F2=35kgm/s²=35Newton =35N

35N>20N

so ,case in which mass is 7kg and acceleration is 5m/s² require greater force
