Supply voltage=60 v, working shown on photo
Answer:
Explanation:
F = Force on the sled = 63 N
m = Mass of sled = 28.7 kg
= Coefficient of kinetic friction = 0.169
g = Acceleration due to gravity =
The force balance of the system is given by
The acceleration of the sled is .
Answer:
a)
b)
c)
d) Δs=4428ft
Explanation:
From the exercise we know the equation of position
a) To calculate the velocity we need to derivate the equation of position
So, v(0) is:
b) To find the two times where the particle stops A and B we need to solve the quadratic equation:
Solving for t
and
c)
d) Δs=4428ft-0ft=4428ft
A) The ball on the small ball is far smaller than the force on the basketball.
B) The total momentum before and after the collision remains constant.
C) We know momentum is conserved so we do:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.1 x 5 + 0.6 x 0 = 0.1 x -4 + 0.6 x v₂
v₂ = 1.5 m/s
