Answer:
a = 8.951 m/s²
Explanation:
given,
angle = 0.52 radians
μ_s = 0.84
μ_k = 0.48
acceleration = ?
using
F + f = m a
mg sin θ + μk mg cos θ = m a
a = g sin θ + μk g cos θ
a = 9.8 x sin 0.52 + 0.48 x 9.8 x cos 0.52
a = 4.869 + 4.082
a = 8.951 m/s²
the magnitude of acceleration is a = 8.951 m/s²
Answer:
Its a MAGNETIC FIELD that can let a magnet attracts more iron dusts
Answer:
5 km/hr because he thinks it moves in the same speed of his...
Given that,
mass m= 5.7 kg
Force of gravity = ?
Since,
Force of gravity acting on earth is equal to the weight and
W= mg
W= 5.7 * 9.81
W= 55.917
or
W= 56 N
Force of gravity acting on Earth by the package is 56 N.
