Answer:
F= 1320 N
Explanation:
Given that
mass ,m= 1100 kg
Acceleration ,a= 1.2 m/s²
We know that ,According to the second law of Newton's
Force = Mass x acceleration
F= m a
F=Force ,a=acceleration
m=mass
Now by putting the values in the above equation
F= 1320 N
Therefore the force on the vehicle will be 1320 N.
Some of the details are missing but we can construct our own statement which would explain the situation.
A rock starts on top of the hill and all of its energy is potential energy. When it starts rolling down the hill this potential energy is being used.
Some of the potential energy is transferred to kinetical energy (energy of motion) and some of it is used to work against friction. Force of friction creates heat and this heat is dissipated into the environment so essentially it is lost.
The statement would be something like this:
As rock rolls down the hill, it loses some of its initial energy due to friction.
Answer:
684.5 is the weight on mars and 1813 on earth
Explanation:
185*3.7=684.5 185*9.8=1813 you multiply for earth by 9.8 because that's the gravity on earth and you multiply by 3.7 because that's the gravity on mars
Acceleration occurs when velocities change.velocity changes either because the speed changes or the direction change.
