    How Many G-Units Did Colonel John P. Stapp Experience Stopping His Rocket Sled?

    i have km/hr of how fast he was moving and how many seconds it took for him to stop and i need to find G units of his acceleration while he was stopping.

    How long does it take for a high-speed train to come to a complete stop?

    84 kph = 23.333333 mps 84m/23.33333 mps = 3.6s

    How Many G-Units Did Colonel John P. Stapp Experience Stopping His Rocket Sled?

    A world's land speed record was set by Colonel John P. Stapp when in March 1954 he rode a rocket-propelled sled that moved along a track at 1020 km/h. He and the sled were brought to a stop in 1.4 s. In g units, what acceleration did he experience while stopping?

    How long does it take for a high-speed train to come to a complete stop?

    i tried converting kph to mps and then seeing how many seconds but the answer was wrong

    How long does it take for a high-speed train to come to a complete stop?

    A high speed train traveling at 84 kph locks its wheels and skids 84 meters before coming to a complete stop. If the rate of slowing down is constant, how many seconds will it take for the train to come to a complete stop?

    Cosine and Sine rules to get magnitude and direction of a resultant force

    No i haven't. Do you know how to find resultant forces with forces and angles from axises? because I have another problem like that and i have no idea how to do them

    Cosine and Sine rules to get magnitude and direction of a resultant force

    Use the cosine and sine rules to determine the magnitude and direction of the resultant of a force of 11 kN acting at an angle of 50 degrees to the horizontal and a force of 6 kN acting at an angle of -30 degrees to the horizontal. helppp please

    How Much Force to Accelerate a Rocket Sled to 1000 km/h in 1.8 Seconds?

    An experimental rocket sled can be accelerated at a constant rate from rest to 1000 km/h in 1.8 s. What is the magnitude of the required net force if the sled has a mass of 700 kg? help please!
