What is the final velocity of a drag racer that has constant acceleration and finishes a
Svetradugi [14.3K]

Answer:

120 mph

Explanation:

Given:

Δx = 0.25 mi

v₀ = 0 mi/s

t = 15 s

Find: v

Δx = ½ (v + v₀) t

0.25 mi = ½ (v + 0 mi/s) (15 s)

v = 0.0333 mi/s

v = 120 mi/h

A cannon tilted upward at 30° fires a cannonball with a speed of 100 m/s. At that instant, what is the component of the cannonba
Sonja [21]

Answer:

the cannonball’s velocity parallel to the ground is 86.6m/S

Explanation:

Hello! To solve this problem remember that in a parabolic movement the horizontal component X of the velocity of the cannonball is constant while the vertical one varies with constant acceleration.

For this case we must draw the velocity triangle and find the component in X(see atached image).

V= Initial velocity=100M/S

cos30=\frac{Vx}{V}

V= Initial velocity=100M/S

Vx=cannonball’s velocity parallel to the ground

Solving for Vx

Vx=Vcos30

Vx=(100m/S)(cos30)=86.6m/s

the cannonball’s velocity parallel to the ground is 86.6m/S

A ball rolls down a hill and hits a box. The momentum of the ball decreases. Which happens to the momentum? Select one of the op
Irina-Kira [14]
<span>So we want to know what happens to the momentum of the ball that rolls down hill and hits a box. So we need to use the law of conservation of momentum which states that the momentum must be conserved. It cant be transformed into inertia or mass. It can only be transferred to other object via some interactions like collisions. So it has to be a. transferred to the box and that is the correct answer. </span>
