OK, many people in my class got a different answer from each other, so could someone verify my work for me please? Here's the problem:
A car (m=1000kg) driving at 20 m/s goes over a ramp angled at 37 degrees with a height of 5 m. How fast is the car traveling when it hits the ground 15 m below the end of the ramp?
my work:
Vyo = 20m/s ( sin37º)
Vyo = 12.0 m/s
Vy = sqrt(vyo^2 + 2gy)
Vy = sqrt ((12m/2)^2 + 2 * 9.8m/s^2 * 15 m)
Vy = 21 m/s
So my answer was 21 m/s
edit: my webspace is down right now so can't post pic
is this correct or am i doing something wrong?
