ASAP A projectile is launched at an
angle of 25° above the horizontal with an
initial velocity (v.) of 32.5 m/s. It reaches the peak of its trajectory in
1.40 seconds. Its horizontal velocity (vx) at the peak of its trajectory is
m/s.

Hey can someone me with my homework

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
