F = ma
We have mass = 0.2kg
and acceleration = 20 m/s^2
So..
F = (0.2)(20)
F = 4 N
Answer:
a) V = 465.9 m/s
b) θ = 70.529°
Explanation:
Let's first calculate angular velocity of earth:
Velocity of a person on Ecuador will be:
For part b, since angular velocity is the same:
Solving for θ:
Answer:
240 kg * m/s
Explanation:
Given
mass (m) = 60 kg
velocity (v) = 4 m/s
Momentum = ?
We know that
Momentum is the product of mass and velocity so
Momentum = m * v
= 60 * 4
= 240 kg * m/s

In order for work to be done a force must be transferred and the object must move.
