To calculate the gravitational force acting on an object given the mass and the acceleration due to gravity, use the following formula.
Fg = m • g
Fg = 1.3 kg • 9.8 m/s^2
Fg = 12.74 N or about 12.7 N.
The solution is C. 12.7 N.
<h3><u>Answer;</u></h3>
Hang time = 3.0 s
Range = 65.06 m
Maximum Height = 11.05 m
<h3><u>Solution</u>;</h3>
Hang time is given by the formula;
T = 2vₒsinθ/g
Thus;
T = 2*(26.2 )sin34.2 / 9.81
= 3.0 s
Range is given by the formula;
R = vₒ²sin2θ/g
= 26.2²sin(2*34.2) /9.81
= 65.06 m
Max height is given by the formula;
H = vₒ²sin²θ/2g
Thus;
H= 26.2²sin²34.2 /(2*9.81)
= 11.05 m
