A manta ray (16000kg) leaps from the water. As it leaves the water it has a velocity of 14.5 km/h [up]. 0.83s after it enters the water again, its velocity has changed to 3.5m/s[down]. What force did the water exert on the manta ray during that time?

Water is heated in a mixing chamber by mixing it with hot water coming from a heater. The mixing chamber loses heat to the surroundings at a rate of 5 kW. The hot water enters the mixing chamber at a rate of 1 kg/s. The mixed water leaves the chamber fully mixed. - The cold water enters the mixing chamber at 200 kPa and 20°C at a velocity of 3 m/s - The hot water enters at a pressure of...

A trained dolphin leaps from the water with an initial speed of 12 m/s. The trainer releases the ball at the horizontal distance of 6.49 m away and the vertical distance of 4.06 m above the water. Suppose the dolphin's launch angle is 45.0 ∘. a)What is the vertical distance between the dolphin and the ball when the dolphin reaches the horizontal position of the ball? We refer to this as the "miss distance." delta h=?m b) If the dolphin's...

A 2400-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 1.90 m/s2 and 1.20 s later an upward velocity of 1.50 m/s . Part A) Determine A....

1) Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 21.5 m/s at an angle θ = 29° above horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position. Part (a) Using v0, θ, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height. Part (b) At what horizontal distance...

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...
