Answer:
306.4J
Explanation:
Given parameters:
Displacement = 50m
Force = 80N
Angle = 40°
Unknown:
Work done = ?
Solution:
Work done is the force applied to move a body through a certain distance.
Work done = Force x displacement cos Ф
Work done = 8 x 50 cos 40 = 306.4J
C) both moving and non-moving objects
As, it is same as the Newton's first law motion
Answer:
Parts 1 and 2 only is the best answer.
Explanation:

The angular velocity of the stepped cylinder is determined as 2.35 rad/s.
<h3>Centripetal acceleration of the cylinder</h3>
The centripetal acceleration of the cylinder is calculated as follows;
F = ma
a = F/m
a = 40/ 36
a = 1.11 m/s²
<h3>Velocity of the cylinder</h3>
a = v²/r
v² = ar
v² = 1.11 x 0.2
v² = 0.222
v = 0.47 m/s
<h3>Angular velocity of the cylinder</h3>
v = ωr
ω = v/r
ω = 0.47/0.2
ω = 2.35 rad/s

Answer:
Explanation:
The force of gravity between two objects is given by:
where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is their separation
In this problem, we have
m1 = m2 = 1170 kg is the mass of each car
r = 28 m is their separation
Substituting,
