Given that,
Mass of the monkey, m = 16.8 kg
The acceleration due to gravity on the Earth, g = 9.8 m/s²
To find,
The gravitational force acting on the monkey.
Solution,
Gravitational force acting on the monkey is equal to its weight. It is given by :
W = mg
Putting all the values,
W = 16.8 kg × 9.8 m/s²
= 164.64 N
Hence, the gravitational force acting on the monkey is 164.64 N.
If we consider that the surface wherein this box is located is frictionless in such a way that the friction does not affect its motion, we can calculate for the horizontal force by multiplying the force with the sine of the angle.
x-component of force = (4 N) x (sin 62°)
= 3.53 N
Answer:
Private jet is 200 mph
Commercial jet is 225 mph
Explanation:
Let the speed of private jet be x mph therefore the speed of commercial jet will be 2x-175 mph
The distance is the same
Speed is distance per unit time hence distance is product of speed and time
Distance by private jet is 9x
Distance by commercial jet is 8(2x-175)
Since the distance is the same
9x=8(2x-175)
9x=16x-1400
7x=1400
X=200
Then 2x-175= 400-175=225
Speed of private jet is 200 mph while commercial jet is 225 mph
