The motorcyclist in Figure wants to jump over "N" cars of height "h" and width "d". To do this, he will use an inclined ramp (´ that does not have friction) at an angle "α" and of height "H". The motorcyclist enters the ramp with a speed "v0" and climbs it without accelerating (since he cannot, due to the absence of friction). You are asked to calculate the minimum speed with which the motorcyclist must enter the ramp, if he wishes to jump over 14 cars arranged as shown in the Figure. The numerical values for the variables are: h = 1 m H = 12 m α = 45◦ d = 2 m

answer

the arrows to the right of earth should point up.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
