Answer:
v=v0 - gt
Explanation:
The equation for velocity is
v=v0 - gt
where v0=14m/s, g=10m/s^2.
in 1 second:
v=14-10=4m/s
it is positive so direction is upwards
in 2 seconds:
v=14-20=-6m/s
it is negative so direction is downwards
Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. ... increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
Answer:
Stress = F / A force per unit area
A = 3.00 cm^2 = 3 E-4 m^2
F = 2.4E8 N/m^2 * 3E-4 m^2 = 7.2E4 N max force applied
F/3 = 2.4E4 N if force not to exceed limit (= f)
f = M a
a = 2.4 E4 N / 1.2 E3 kg = 20 m / s^2 about 2 g
<h2>Answer :</h2><h2 />
Work is the amount of energy transferred. As per the formula
Work = Force x Distance [moved toward the direction of the force]
So as per the formula
<u>Solution : </u>
Force = 825 N
Distance = 35 m
Work = 825 (n) x 35 (m)
Work = 28875 Joules
