First let us calculate for the angle of inclination using
the sin function,
sin θ = 1 m / 4 m
θ = 14.48°
Then we calculate the work done by the movers using the
formula:
W = Fnet * d
So we must calculate for the value of Fnet first. Fnet is
force due to weight minus the frictional force.
Fnet = m g sinθ – μ m g cosθ
Fnet = 1,500 sin14.48 – 0.2 * 1,500 * cos14.48
Fnet = 84.526 N
So the work exerted is equal to:
W = 84.526 N * 4 m
<span>W = 338.10 J</span>
Force = mass * acceleration. Therefore, given the force of 120 N and the mass of 46 kg:
120 N = 46 kg * acceleration
120 kg-m/s^2 = 46 kg * acceleration (in m/s^2)
acceleration = 120/46 = 2.61 m/s^2
False because -2 occurs twice
Answer:
P= IV = (0.50 A)(120 V) = 6.0x101 W R 4.
Explanation:
hope it will help
Its 200 west but 100 north, if it north was 200, the answer would be C, but being the case of 200, 100 on two different answers that has north and west wouldn't be right
