81. •Astro The froghopper, a tiny insect, is a remarkable
jumper. Suppose you raised a colony of the little critters
on the Moon, where the acceleration due to gravity is
only 1.62 m/s?. If on Earth a froghopper's maximum
height is b and maximum horizontal range is R, what
would its maximum height and range be on the Moon in
terms of h and R? Assume a froghopper's takeoff speced
is the same on the Moon and on Earth.
• A red car and a green caron adjacent lanes move towards each other, at t=0, the red car is at xred=0 and the green car is at xgreen=220m.
If the red car has a velocity of 60km/hr, the cars each passed each other at x=44.5m, and if it has a constant velocity of 40km/hr, they pass each other at 76.6m. What is a). The initial velocity b). The acceleration of the green car?
*****The initial velocity of the red car is 20km/hr........x= 44.5mIf it travels at a constant velocity of 40km/hr......x= 76.6m*******Note the correction in the question
3. Another rocket lifts off and accelerates upward at a steady 3.30 m/s2• When it is 235 mabove the launch pad, it discards a used fuel canister. Once it is disconnected, the only forceacting on the canister is gravity (ignore air resistance).(a.} How high is the rocket when the canister hits the launch pad?(b.) What total distance did the canister travel between its release and its crash onto thelaunch pad?
