The acceleration of the box up the ramp is 9.65 m/s².
<h3>
What is the magnitude of acceleration of the box?</h3>
The magnitude of the acceleration of the box is calculated by applying Newton's second law of motion as shown below;
F(net) = ma
where;
- m is the mass of the box
- a is the acceleration of the box
The net force on the box is calculated as follows;
F(net) = F - Ff
F(net) = F - μmgcosθ
where;
- θ is the inclination of the plane
- μ is coefficient of friction
F(net) = 170 - (0.3 x 15 x 9.8 x cos55)
F(net) = 144.7
The acceleration of the box is calculated as;
a = F(net) / m
a = (144.7) / (15)
a = 9.65 m/s²
Thus, the acceleration of the box up the ramp is 9.65 m/s².

#SPJ4
The power of a machine is the work/time ratio for that particular machine
Its the rate of doing work.
Answer:
There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
Explanation:
Answer:
mass is directly proportionate to magnetic force.
Explanation:
the more mass the more magnetic force
<h2>
Answer:</h2>
1000N
<h2>
Explanation:</h2>
From Newton's third law of motion, for every action there is an equal and opposite reaction. In other words, when two bodies are in collision, the forces acting between these bodies are equal in magnitude and opposite in direction.
In the case presented in the question, the bodies are the <em>golf cart</em> and the<em> car. </em> During collision, the <em>golf car</em> strikes the car with a 1000N of force (that is the <em>action</em>). Consequential of this, though in the opposite direction, the <em>car </em>will apply an equal force of 1000N (that is the <em>reaction</em>) on the <em>golf car.</em>
<em></em>
Therefore the car applied a force of 1000N on the golf cart.
