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.

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.
