Three toy boats with the same mass were in a lake. The blue boat's initial speed was 8 km/hr. Its final speed was 3 km/hr. The
orange boat's
intial speed was 0 km/hr, and its final speed was 5 km/hr. The gray boat's
initial speed was 12 km/hr and its final speed was 17 km/hr. Two boats were
moving and one was stopped. Each boat got bumped by another boat, but
not in the same direction. All the boats changed speed as a result of being
bumped. Which toy boat(s) experienced the strongest force when it was
bumped? How do you know?*

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
