A dare devil decide to jump a canyon. Its walls are equally high and 10m apart. He takes off by driving a motor cycle up a short ramp sloped at an angle of 15 degrees. What minimum speed must he have in order to clear the canyon.
<br>This is a case of projectile motion.
<br>If a body is projected upwards (no angles involved) it will reach a height where its Kinetic Energy gets converted to potential form. At this point we can write,
<br>(1/2)m u^2 = m g h
<br>U^2 = 2gh
<br>where h is the ...
