Answer: 586.60N/m
Explanation:
In this scenario, the elastic potential energy of the spring is converted into potential energy.
0.5*K*x^2 = mgh
Thus K = 2mgh/x^2
=(2*2.90*10^-2*9.8*7.23)/(8.37*10^-2)^2
=586.599
Therefore K = 586.60N/m
Answer:
2000 kg
Explanation:
Given that Which will have a larger momentum when moving at the same speed: a 2,000-kg truck or a 1,000-kg sedan
According to the definition of momentum, momentum is the product of mass and velocity.
That is,
Momentum = mass × velocity
Since velocity or speed is the same, then, the one of higher mass will have a greater momentum.
Therefore, the 2000 kg truck will have the greater momentum.
March 20 and September 22
25/1500 is equal to 0.8/x
0.8*1500 is equal to 1200
1200/25 is equal to 48 N
When the object is big enough to contract itself into a ball.
