Explanation:
Let us assume that the maximum allowable horizontal distance be represented by "d".
Therefore, torque equation about A will be as follows.
d =
d = 0.409 m
Thus, we can conclude that the maximum allowable horizontal distance from the axle A of the wheelbarrow to the center of gravity of the second bag if she can hold only 75 N with each arm is 0.409 m.
False The airplane had an increase of 100kph over a 2 hour period. 100 / 2 = 50. so that would be 50 kph average acceleration.
Answer:
RIGHT
Explanation:
given,
mass of box = 250 kg
speed of the truck = 25 m/s
static friction µs = 0.7
g = 10 m/s²
to find direction of friction on the box
truck is moving in left direction and suddenly in front of truck a car stops then the driver hit the brake hard so at that moment the box on the trailer will have the tendency to move left so to oppose its movement friction force will be on RIGHT
Pressure= F/A
Given, F=30 N
Area=20 m^2
Putting values in formula,
Pressure = 30/20
=3/2
=1.5 Pascals
Yes but they not supposed to
