This is simply F=ma so 70N/30m/s^2 will give you the max mass which would be in kg, and the mass would be 2.333333kg a very light plane I might say
Answer:
8400 N
Explanation:
We are given that
Mass,m=1.2 kg
Initial speed,u=-8 m/s
Final speed,v=6 m/s
Time,
We have to find the magnitude of the average force on the ball during this collision.
Change in momentum,=
Average force,
Using the formula
Hence, the magnitude of the average force on the ball during this collision=8400 N
Answer:
216
you have to change the meters per second to meters per minute, so you multiply .12 by 60 and get 7.2, then you multiply 7.2 meters per minute by 30 minutes and get 216
First thermal energy (heat) is not the same thing as temperature. Thermal energy is internal energy held by the molecules but the temperature is the is the effect of the heat. Temperature is the measurement of the heat energy. Also, thermal energy depends on the size of the matter but the temperature isn't, it's just the average heat energy held by the matter.
