I need help with these two physics problems

7 Part C - Projectile motion A student solving a physics problem for the range of a projectile has obtained the expression v3 sin (26) 9 where 1):; = 37.2 meter/ second, 9 = 14.10 , and g = 9.80 meter/second2. Use your calculator to evaluate R. D View Available Hint(s) C 31.5 meter /'\\ ' t 10.5 meter 0' 66.7 meter 0 69.5 meter Part D - Capstone problem A group of physics students hypothesize that for an experiment they are performing, the speed of an object sliding down an inclined plane will be given by the expression v= 2gd(sin (0) - Hk cos (0)). For their experiment, d = 0.725 meter, 0 = 45.0 , /k = 0.120, and g = 9.80 meter /second". Use your calculator to obtain the value that their hypothesis predicts for v.
