Answer:
Explanation:
We will use the equation F - f = ma, which is a fancy way of stating Newton's 2nd Law.
F = +50.0,
f = -30.0,
m = 7.60 kg. Therefore:
50.0 - 30.0 = 7.60a and
20.0 = 7.60a and
a = 20.0/7.60 so
a = 2.63 m/s/s to the right
90 kilometers because you need to multiply 40 by 2 and then you get 80 and finally you add 10 and get 90 kilometers
Answer:
Explanation:
Given
Wheels are rotating with constant angular velocity let say
Presence of constant angular velocity show that there is no angular acceleration thus there is no tangential acceleration.
But any particle on the rim will experience a constant acceleration towards center called centripetal acceleration.
(a) yes, there will be tangential velocity which is given by
where r=radial distance from center
(b)tangential acceleration
there would be no tangential acceleration as velocity is constant
(c)centripetal acceleration
Yes, there will be centripetal acceleration given by
