Answer:
v = at + u
Explanation:
acceleration, a = constant
As we know that acceleration is the rate of change of velocity
integrate on both sides
v = at + u
Where, u is the integrating constant and here it is equal to the initial velocity
Now we know that the rate of change of displacement is called velocity
Integrate on both sides
where, xo is the integrating constant which is initial position of the particle.
Answer:
m = 28.7[kg]
Explanation:
To solve this problem we must use the definition of kinetic energy, which can be calculated by means of the following equation.
where:
Ek = kinetic energy = 1800 [J]
m = mass [kg]
v = 11.2 [m/s]
