If you were somehow magically transported to Jupiter, your mass
would not change, but your weight would become roughly 2.5 times
your Earth weight.
This cab be solve using Newtons second law of motion :
F = ma
Where F is the force applied
A is the accelaration = v/s
V is the velosity
S is the time
M is the mass
F = (2100 kg)*( 96km/hr)( 1000m/ 1km)( 1 hr/3600 s) / 3.5 s
F = 16000 N is the force applied
Answer:
Cape Point lighthouse
Explanation:
The lighthouse is located South of Cape Town, at a point where boats turn to go around the tip of Africa.
The new lighthouse has the most powerful light of all the lighthouses in South Africa, with a power of 10 megacandelas. That's why it's being visible for up to 63 km around.
It's a very important lighthouse helping to conduct the traffic around dangerous waters where 2 oceans meet.
Answer:
364.4 J
Explanation:
I = Moment of inertia of the forearm = 0.550 kgm²
v = linear velocity of the ball relative to elbow joint = 17.1 m/s
r = distance from the joint = 0.470 m
w = angular velocity
Using the equation
v = r w
17.1 = (0.470) w
w = 36.4 rad/s
Rotational kinetic energy of the forearm is given as
RKE = (0.5) I w²
RKE = (0.5) (0.550) (36.4)²
RKE = 364.4 J
Answer:
0.958891203 m/s²
Explanation:
N = Weight of crate = 900 N
= Coefficient of friction = 0.25
Force of friction acting on the force applied
Force used to pull the crate
The net force is
Acceleration is given by
The magnitude of the acceleration of the crate is 0.958891203 m/s²
