initial speed of the stuntman is given as
![v = 28 m/s](https://tex.z-dn.net/?f=v%20%3D%2028%20m%2Fs)
angle of inclination is given as
![\theta = 15 degree](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2015%20degree)
now the components of the velocity is given as
![v_x = 28 cos15 = 27.04 m/s](https://tex.z-dn.net/?f=v_x%20%3D%2028%20cos15%20%3D%2027.04%20m%2Fs)
![v_y = 28 sin15 = 7.25 m/s](https://tex.z-dn.net/?f=v_y%20%3D%2028%20sin15%20%3D%207.25%20m%2Fs)
here it is given that the ramp on the far side of the canyon is 25 m lower than the ramp from which she will leave.
So the displacement in vertical direction is given as
![\delta y = -25 m](https://tex.z-dn.net/?f=%5Cdelta%20y%20%3D%20-25%20m)
![\delta y = v_y * t + \frac{1}{2} at^2](https://tex.z-dn.net/?f=%5Cdelta%20y%20%3D%20v_y%20%2A%20t%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20at%5E2)
![-25 = 7.25 * t - \frac{1}{2}*9.8* t^2](https://tex.z-dn.net/?f=-25%20%3D%207.25%20%2A%20t%20-%20%5Cfrac%7B1%7D%7B2%7D%2A9.8%2A%20t%5E2)
by solving above equation we have
![t = 3.12 s](https://tex.z-dn.net/?f=t%20%3D%203.12%20s)
Now in the above interval of time the horizontal distance moved by it is given by
![d_x = v_x * t](https://tex.z-dn.net/?f=d_x%20%3D%20v_x%20%2A%20t)
![d_x = 27.04 * 3.12 = 84.4 m](https://tex.z-dn.net/?f=d_x%20%3D%2027.04%20%2A%203.12%20%3D%2084.4%20m)
since the canyon width is 77 m which is less than the horizontal distance covered by the stuntman so here we can say that stuntman will cross the canyon.
Answer:
In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.

Explanation:
Both these questions are based on the Universal Law of Gravitation, which is given by :
F = Gm1m2 / r²
2) F = 6.67 x 10⁻¹¹ x 8 x 10³ x 1.5 x 10³ / 1.5 x 1.5
F = 6.67 x 10⁻⁵ x 8 / 1.5
F = 35.57 x 10⁻⁵ N
3) F = 6.67 x 10⁻¹¹ x 7.5 x 10⁵ x 9.2 x 10⁷ / 7.29 x 10⁴
F = 6.67 x 10⁻³ x 7.5 x 9.2 / 7.29
F = 63.13 x 10⁻³ N
Explanation:
Draw a free body diagram for each disc.
Disc A has three forces acting on it: 86.5 N up, T₁ down, and Wa down.
∑F = ma
86.5 N − T₁ − Wa = 0
Wa = 86.5 N − T₁
ma × 9.8 m/s² = 86.5 N − 55.6 N
ma = 3.2 kg
Disc B has three forces acting on it: T₁ up, T₂ down, and Wb down.
∑F = ma
T₁ − T₂ − Wb = 0
Wb = T₁ − T₂
mb × 9.8 m/s² = 55.6 N − 36.5 N
mb = 1.9 kg
Disc C has three forces acting on it: T₂ up, T₃ down, and Wc down.
∑F = ma
T₂ − T₃ − Wc = 0
Wc = T₂ − T₃
mc × 9.8 m/s² = 36.5 N − 9.6 N
mc = 2.7 kg
Disc D has two forces acting on it: T₃ up and Wd down.
∑F = ma
T₃ − Wd = 0
Wd = T₃
md × 9.8 m/s² = 9.6 N
md = 0.98 kg
