Two blocks start from rest and start to accelerate. The coefficient of kinetic friction between a 7.00-kg object and the incline is 0.275 (see figure). What is the acceleration experienced by each of the two objects?

Ascientific blank must be testable and capable of being proven false?

Which is an example of an exothermic process?

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?
