Acceleration toward the center of a curved path is called

Physics
1 answer:
Serggg [28]3 years ago
7 0

Answer:

Centripetal acceleration.

Explanation:

Centripetal acceleration is a property of a body moving in a uniform circular path and it is directed radially towards the center of the circle in which body is rotating.

The force which causes this acceleration is centripetal force which is also directed towards the center of the circle and pulls the body towards its center.

It is calculated through following formula

a=v^2/r

where v is velocity and r is the radius of the circle.

A snowmobile has an initial velocity of 3.0 m/s
dexar [7]
My answer to the problem is as follows:
 
<span>1. Use the kinematic formula 

Vf = Vi + a*t 

for a, Vi = 3.0 m/s, a = 0.5 m/s/s, and t = 7.o s. 

for b, Vf = 0, Vi = 3.0 m/s, and a = -0.60 m/s/s. 

I hope my answer has come to your help. God bless and have a nice day ahead!

A football player at practice pushes a 60 kg blocking sled across the field at a constant speed. The coefficient of kinetic fric
avanturin [10]

Answer:

C. 180 N

Explanation:

m = mass of the blocking sled = 60 kg

\mu = Coefficient of kinetic friction = 0.30

f = kinetic frictional force acting on the sled

kinetic frictional force acting on the sled is given as

f = \mu mg = (0.30) (60) (10) = 180 N

F =Force applied

For the sled to move at constant speed, the applied force must be same as the frictional force

F = f\\F = 180 N

A thin film soap bubble (n=1.35) is floating in air. If the thickness of the bubble wall is 300nm, which of the following wavele
iren [92.7K]

Answer:

540 nm

Explanation:

According to the question,

The refractive index of the soap bubble, n=1.35.

The thickness of the soap bubble wall is, t=300 nm.

Now, for constructive interference of soap bubble.

2nt=(m+\frac{1}{2})\lambda.

Now for first order m=1.

Therfore,

\lambda =\frac{4}{3} tn

Substitute all the variables in the above equation.

\lambda =\frac{4}{3} (1.35)(300 nm).

Therefore,

\lambda =540 nm.

Therefore the visible light wavelength which is strongly reflected is 540 nm.

James Bond is trying to escape his enemy on a speedboat but
SVEN [57.7K]

Answer:

100 m/s

Explanation:

Mass the mass of Bond's boat is m₁. His enemy's boat is twice the mass of Bond's i.e. m₂ = 2 m₁

Initial speed of Bond's boat is 0 as it won't start and remains stationary in the water. The initial speed of enemy's boat is 50 m/s. After the collision, enemy boat is  completely stationary. Let v₁ is speed of bond's boat.

It is the concept of the conservation of momentum. It remains conserved. So,

m_1u_1+m_2u_2=m_1v_1+m_2v_2

Putting all the values, we get :

0+(2m_1)50=m_1v_1+(2m_2)(0)\\\\100m_1=m_1v_1\\\\v_1=100\ m/s

So, Bond's boat is moving with a speed of 100 m/s after the collision.
