The final velocity of the ball is +9.25 m/s

Explanation:

We can solve the problem by using the impulse theorem, which states that the impulse exerted on the ball (product of the force exerted and the duration of the collision) is equal to the change in momentum of the ball:

F\Delta t = m(v-u)

where

F is the force exerted

\Delta t is the duration of the collision

m is the mass of the ball

v is the final velocity

u is the initial velocity

In this problem, we have

m = 0.060 kg

u = -32 m/s

\Delta t = 45 ms = 0.045 s

F = +55 N

Therefore we can solve for v to find the final velocity:

v=u+\frac{F\Delta t}{m}=-32 + \frac{(55)(0.045)}{0.060}=+9.25 m/s

Which describes an object in projectile motion? Check all that apply.A.Gravity acts to pull the object downB.The object moves in
irina1246 [14]

Answer:

A.Gravity acts to pull the object down

D.The object’s inertia carries it forward.

E.The path of the object is curved.

Explanation:

The motion of a projectile consists of two independent motions:

- A uniform motion along the horizontal direction, with constant horizontal speed

- A vertical motion with constant acceleration of g = 9.8 m/s^2 downward (acceleration due to gravity), due to the presence of the force of gravity, so the vertical velocity changes (increases in the downward direction)

As a result, the combined motion of the projectile has a curved trajectory (parabolic, more specifically). So the following options are correct:

A.Gravity acts to pull the object down --> gravity acts along the vertical direction

D.The object’s inertia carries it forward. --> there are no forces acting along the horizontal direction (if we neglect air resistance), so the horizontal motion continues with constant speed

E.The path of the object is curved
