a. What are Bob's initial velocities in the horizontal and vertical direction?

b. What is Bob's initial position in the horizontal and vertical direction?

c. What is Bob's acceleration in the horizontal and vertical directions?

d. How long is Bob in the air?

e. How far from the end of the ramp does he land?( the distance R shown in the picture below)?

20 m/s 450 10 m

    I need help with this physics on projectile motion problem! 4.83: A motorcycle daredevil wants to set a record for jumping over burning school buses. He has hired you to help with the design. He intends to ride off a horizontal platform at 40m/s, cross the burning buses in a pit below him, then land on a ramp sloping down at 20∘. It's very important that he not bounce when he hits the landing ramp because that could cause him...

    A motorcycle daredevil plans to ride up a 2.1 m high 23.5 degree ramp, sail across a 8 m wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as he starts up the ramp. He is going 12 m/s at that instant, and the rolling friction of his rubber tires (coefficient 0.02) is not negligible. Does...
