Explanation:
It is given that,
Mass of the block, m = 3.57 kg
It is drawn to a distance of, d = 4.06 m
Horizontal force acting on the rope, F = 7.68 N
Angle above horizontal,
(A) The work done by the rope on the block is W. It can be calculated as :
W = 30.11 joules
(b) Let is the coefficient of kinetic friction between block and floor. According to the free body diagram of the given problem. At equilibrium,
Hence, this is the required solution.
S= 1/2 x 182 x t = 1688.3
t = 1688.3 / 91
time = 18.55 seconds
Answer:
-15.67287 N/C
Explanation:
= Location of electron =
= Location of electric field =
e = Charge of electron =
k = Coulomb constant =
Distance between the points is
Electric field is given by
The magnitude of the electric field is 15.67287 N/C
The direction is negative as the electron has negative charge.
Answer:
#See solution for details.
Explanation:
Newton's Second law of motion states that :- the rate of change of momentum is directly proportional to the force applied on an object or system..
The force applied on an object of mass m is directly proportional to the product of mass and acceleration:
-Let be the initial momentum and be the final momentum.
#also let be the initial velocity and the final.
Momentum,:
#where k is the constant of proportionality. Given the direct proportion, k=1.
#The unit is in kgm/s but usually equated to N, 1kgm/s=1N
