What force is required to give an object with mass 2000 kg an acceleration of 3.5 m/s2
2 answers:
<u>Answer:</u> The force exerted on the object is 7000 N
<u>Explanation:</u>
Force is defined as the push or pull on an object with some mass that causes change in its velocity.
It is also defined as the mass multiplied by the acceleration of the object.
Mathematically,
where,
F = force exerted on the object
m = mass of the object = 2000 kg
a = acceleration of the object =
Putting values in above equation, we get:
Hence, the force exerted on the object is 7000 N

Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy
Spring potential energy =potential energy due to elevation
0.5*k*x²= mg=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy
spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*
10812.88 *2.3²=430*
=11.53 m/s
Answer:
Heat required to raise the temperature of the aluminium is 4750 J
Explanation:
As we know that the heat energy required to raise the temperature of the aluminium is given as
here we know that
m = 50 g
so we have
