Answer:
Therefore, the centripetal acceleration of the SUV is <u>3 times</u> ao of the compact car.
Explanation:
FOR SUV:
where,
ac_suv = centripetal acceleration of the SUV = ?
m = mass of SUV = 6000 kg
v = speed of SUV = vo
r = radius of path
Therefore,
---------------- equation (1)
FOR CAR:
where,
ao = centripetal acceleration of the car = ?
m = mass of car = 2000 kg
v = speed of car = vo
r = radius of path
Therefore,
--------------------- equation (2)
Dividing equation (1) by eq(2):
Therefore, the centripetal acceleration of the SUV is <u>3 times</u> ao of the compact car.
Answer:
Explanation:
Block A sits on block B and force is applied on block A . Block A will experience two forces 1) force P and 2 ) friction force in opposite direction of motion . Block B will experience one force that is force of friction in the direction of motion .
Let force on block A be P . friction force on it will be equal to kinetic friction, that is μ mg , where μ is coefficient of friction and m is mass of block A
friction force = .4 x 2.5 x 9.8
= 9.8 N
net force on block A = P - 9.8
acceleration = ( P - 9.8 ) / 2.5
force on block B = 9.8
acceleration = force / mass
= 9.8 / 6
for common acceleration
( P - 9.8 ) / 2.5 = 9.8 / 6
( P - 9.8 ) / 2.5 = 1.63333
P = 13.88 N .

You can do experience pain in many ways. Some mental pain is loss of a loved one, or loss of a pet. Some physical pain is falling and skinning your knee, or breaking a bone. Please mark me brainliest! :)
