MoneyPenny watches James Bond on a 10m high bridge as a 9.5 foot high train runs underneath it at 12 m/s to her right. If Bond runs to the right and jumps off the bridge at an angle of 30 degrees above the horizontal with as speed of 5 m/s. What is the relative velocity of the train to Bond when he lands on it? (That is just before impact not after impact)

3. (Impulse/Momentum) A 120 lbs. girl takes a running start and jumps onto a 50 lbs. cart, cart A. Her horizontal velocity when she lands on cart A is 15 ft/s. The girl rides cart A until she is 1.5 ft from cart B. She then jumps off cart A towards cart B with a velocity relative to cart A of v-5 ft/s. She leaves the cart at an angle of 25 degrees. Cart B has a weight of 150...

Bond....James Bond is out in his specially equipped BMW when he is attacked by “Bad Guys”. Traveling at 220 km/h James realizes that he is about to plunge over a cliff so he presses the Big Red Button and ejects. The seat is propelled upward at an angle of 34 degrees to the horizontal and a speed of 197 km/h , relative to the car. If the cliff is 53 m high: a. How long is James in the air?...

Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as positive y-direction. E....
