Initial Velocity formulas are used to find the initial velocity of the moving body if some of the terms are given. Initial velocity can be formulated in a unit of a meter per second i.e. ms^{-1}. ms−1.
Answer:
The compress of the spring is 0.495.
Explanation:
Given that,
Mass = 50 kg
Spring constant = 8000 N/m
height = 2.0 m
We need to calculate the compress of the spring
Using law of conservation of energy
Where, m = mass
g = acceleration due to gravity
h = height
k = spring constant
x = distance
Put the value into the formula
Hence, The compress of the spring is 0.495.
Answer:
The answer is D a car.
