but how do you get it into G units?

a= vf-vo _____ t thank you!

oh so it's original and then 0 is the final?

That is the only velocity given so I'm not sure.

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.

I don't know what formula to use

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

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?

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

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?

thank you thank you thank you!

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

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

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!
