Answer:
mass=0.50kg
force=25N
acceleration =?
Now,
force=m×a
25=0.50×a
25÷0.50=a
50=a
acceleration =50m/s^2 answer!!!!
hope this may help you!!!!
Answer:
72 kilometres per hour
Explanation:
The formula for calculating speed is distance/time.
So to work this out you would convert 2 minutes into hours. You would divide 2 by 60 to convert it into hours. This is because the standard unit for speed with kilometres is kilometres per hour. Then you would divide 2.4 by that.
1)Divide 2 by 60:

2) Divide 2.4 by 0.0333333.

3) Round it.
