find the minimum velocity for which the range is 39.2m

Asked by shivam upadhyaya | 10th Jun, 2013, 03:55: PM

Expert Answer:

range = v^2 sin2A/g where A is the angle at which projectile is launched and v is the velocity. 
v = sqrt(range*g/sin2A)
To find the minimum velocity, sin2A = 1
v = sqrt(39.2*9.8) = 19.6 m/s
