Given:
v = 50.0 m/s, the launch velocity
θ = 36.9°, the launch angle above the horizontal
Assume g = 9.8 m/s² and ignore air resistance.
The vertical component of the launch velocity is
Vy = (50 m/s)*sin(50°) = 30.02 m/s
The time, t, to reach maximum height is given by
(30.02 m/s) - (9.8 m/s²)*(t s) = 0
t = 3.0634 s
The time fo flight is 2*t = 6.1268 s
The horizontal velocity is
u = (50 m/s)cos(36.9°) = 39.9842 m/s
The horizontal distance traveled at time t is given in the table below.

Answer:
Mass, m = 16.02kg
Explanation:
Given the following data;
Force, F = 157N
Since it's a free fall, acceleration, a = g = 9.8m/s² (acceleration due to gravity).
To find the mass;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- F represents force measured in Newton.
- m represents the mass of an object measured in kilograms.
- a represents acceleration measured in meter per seconds square.
<em>Making mass (m) the subject of formula, we have;</em>
<em>Substituting into the equation;</em>

Mass, m = 16.02kg
<em>Therefore, the mass of the rock is 16.02kg.</em>
Answer: from vector law opposite we minus
Hence
425n-300n=125n to the right
Hints in left vector have -Ve sign while right have +Ve sign
It’s not true! Due to the earth already moving around earth it’s not possible for earth to meet the Apple so instead the Apple meets earth due to the gravitational pole! If earth met the Apple it would mess up circling the sun causing us to meet out demise
