A fish swimming in horizental plane has velocity vi=(4j+j)m/s at a point in the ocean when aposition relative with acertain rock is Ri=(10i-4j)m After The Fish Swimms With Constant Acceleration For 20s it isvelocity is Uf=(20i-5j) m/s. A) find The Accelaration Of The Fish
2) If The Fish Maintains This Constant Acceleration Where Is It At T=25s

Which articulations allow for greatest range of motion?

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
