The froghopper, Philaenus spumarius, holds the world record for insect jumps. When leaping at an angle of 58.0 above the horizontal, some of the tiny critters have reached a maximum height of 52.7 above the level ground.A) What was the takeoff speed for such a leap? v= 3.79m/sB) What horizontal distance did the froghopper cover for this world-record leap?
A block is projected up a frictionless inclined plane with initial speed v0 = 8.50 m/s. The angle of incline is ? = 27.7°. How far up the plane does it go
An elvator can carry a max load of 1600kg is moving up with a constant speed of 2 m/s. The frictional force opposing the motion is 3320N. Determine the max power delivered by the motor to the elvator in HP.
