Answer:

Negative acceleration occurs when an object slows down in the positive direction.

Negative acceleration occurs when an object speeds up in the negative direction.

Positive acceleration occurs when an object speeds up in the positive direction.

Positive acceleration occurs when an object slows down in the negative direction.

Explanation:

Acceleration is the increase in speed that an object shows or experiments in a certain time, so you have positive and negative acceleration depending on the negative and negative direction, for example when using the vertical plane falling would be negative direction and going up would be the positive direction, so any increase in speed in the positive direction that would be a positive acceleration, increase in the negative would be negative acceleration, and decreases in both would mean an opposite acceleration.

The linear speed of the basketball at the bottom in m/s is 37.41 m/s.

The mechanical energy basket ball is conserved and the basket ball starts from rest. and roll down a hill of height 70m.

If mechanical energy is conserved,

Potential energy at top + kinetic energy at top = potential energy at bottom + kinetic energy at bottom.

At bottom, there is no potential energy, and at top, there is no kinetic energy.

Potential energy at top = kinetic energy at bottom.

Mgh = 1/2Mv²

M is the mass of the basketball,

v is the linear speed at the bottom,

h is the height of the ball.

Putting values,

v = √(2gh)

v = √(2x10x70)

v = 37.41m/s.

The speed of the basketball at the bottom is 37.41 /s.

A block that has a mass M = 500 g is hanging at rest on a light string. A projectile with a mass m = 15 g moving horizontally wi

stira [4]

Answer:

2.8m

Explanation:

Convert to metric:

500g = 0.5 kg

15g = 0.015 kg

Assuming elastics collision, we could use the law of momentum conservation to calculate the speed of black and projectile post-collision V:

mv = (M + m)V

$V = \frac{mv}{m+M} = \frac{0.015*255}{0.5 + 0.015} = 7.43 m/s$

This would make the system moves up, which convert its kinetic energy to potential energy. By the law of energy conservation when the mass reaches its highest point (aka speed = 0)

$E_k = E_p$

$0.5(M+m)V^2 = (M+m)gh$

$h = \frac{V^2}{2g} = \frac{7.43^2}{2*9.81} = 2.8m$

You decide to take your middle school science class to the bowling alley for some “hands-on”

Reika [66]

Answer:

(1) is incorrect and (2) is correct.

Explanation:

There is a force of friction opposing the motion, but as soon as Jill let go of the ball, there is no force pushing the ball onward. Therefore, the only forces acting on the ball is the force of friction and air resistance. (still friction)
