Question

Water leaves a hose at a rate of 3.6-kg per 2.5-s with a speed of 20.5-m/s and is aimed at a toy car at the exact moment the car is hit the water slows down to 3.1-m/s (That is, we ignore any splashing back.) What is the force exerted by the water on the toy car?

Expert Solution

Step 1

Given

Initial velocity is v₀= 20.5 m/s

Part A) calculate the horizontal component of the average force, in newtons, on the person if he stopped by a padded dashboard that compressed an average of .85cm. Part B) calculate the horizontal component of the average force, in newtons, on the person if he is stopped but an air bag that compresses an average of 13.5 cm

A boy on a 2.0 kg skateboard initially at rest tosses an 8.0 kg jug of water in the forward direction. Find theboy’s mass if the jug has a speed of 3.0 m/s relative tothe ground, and the boy and skateboard move in theopposite direction at 0.60 m/s
Squids rely on jet propulsion when a rapid escape is necessary, providedthey have filled their mantle with water prior to escape. An empty 1.5kg squid initially drifting at 1.6m/s pulls in 0.10kg of water in its mantle, then ejects this water at a remarkable 45m/s. How fast is this squid moving right after filling up with water?
Two 3011 kg train cars toward each other (Car A at 0.8 m/s, Car B at -2.13 m/s) on a level track. After they collide and couple together, what is the final velocity of the two-car object?

Squids rely on jet propulsion to move around. A 1.50 kg (including the mass of the water inside the squid) squid drifting at 0.40 m/s suddenly ejects 0.10 kg of water to get itself moving at 2.50 m/s. If drag is ignored over the small interval of time needed to expel the water (why can we do this?), what is the water’s ejection speed relative to the squid? Include sketch
