Answer:
Workdone = 25500Nm
Explanation:
Given the following data
Force = 425N
Distance = 60m
To find the workdone
Workdone = force *distance
Substituting into the equation, we have
Workdone = 425*60
Workdone = 25500Nm
Answer:
Both vehicles experience the same change in momentum
Explanation:
Let m represent the mass of the vehicle, and 2m represent the mass of the large truck, and let v represent their initial speed, we have;
The total initial momentum, given as follows;
= 2·m·v - m·v = m·v
The total final momentum, = (2·m + m) ×
By the principle of conservation of linear momentum, the total initial momentum = The total final momentum
m·v = (2·m + m) ×
m·v = 3·m·
∴ v = 3 ×
= v/3
The change in the momentum for the large truck = 2·m·v - 2·m·
Therefore;
The change in the momentum for the large truck = 2·m·v - 2·m·v/3 = 2·m·(v - v/3)
The change in the momentum for the large truck = 2·m·(v - v/3) = 2·m·2·v/3 = 4·m·v/3
The change in the momentum for the car = m·v - m·(-) = m·v - m·(-v)/3 = m·v + m·(v)/3 = 4·m·v/3
Therefore, the change in the momentum for the large truck = The change in the momentum for the car and both vehicles experience the same change in momentum.

Explanation:
The mechanical advantage of a simple machine is the ratio between the output force (load) and the input force (effort).
For a perfect wedge (efficiency of 100%), the mechanical advantage is also given by:
where:
L is the length of the slope
w is the width of the wedge
For the wedge in this problem, we have:
L = 5.1 cm is the slope length
w = 2.8 cm is the width
Therefore, the mechanical advantage is:
