The coordinate axes of the reference frame S′ remain parallel to those of S, as S′ moves away from S at a constant velocity v⃗ SS′=(4.0iˆ+3.0jˆ+5.0kˆ)m/s. (a) If at time t = 0 the origins coincide, what is the position of the origin O′ in the S frame as a function of time? (b) How is particle position for r⃗ (t) and r⃗ ′(t), as measured in S and S′, respectively, related? (c) What is the relationship between particle velocities v⃗ (t)andv⃗ ′(t)? (d) How are accelerations a⃗ (t)anda⃗ ′(t) related?

Ineed the answer to question 1 , i’m desperate

Two pans of a balance are 24.1 cm apart. the fulcrum of the balance has been shifted 1.33 cm away from the center by a dishonest shopkeeper. by what percentage is the true weight of the goods being marked up by the shopkeeper? assume the balance has negligible mass. answer in units of %.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
