Answer: 1.32 m/s^2
Explanation:
Centripetal acceleration is given by the formula
a = ( v^2 ) / r
where a is centripetal acceleration, v is velocity and r is radius.
We know that,
v = 5 m/s
r = 19m
Now,
a = ( v^2 ) / r
a = ( 5^2 ) / 19
a = 25 / 19
a = 1.32 m/s^2
Given: Please see the attached image below.
To be able to
subtract vectors, we can either use the parallelogram method or the triangle
method. Take note that the only difference is that alternatively adding vectors
A and B, we will instead be adding A and – B. When we ponder of vector subtraction, we must
anticipate about it in terms of adding a negative vector. A negative vector has the same magnitude as the
original vector, however, it has an opposite direction.
So in this problem, the two vectors that will have the
largest magnitude are A & F when subtracted (i.e., when one vector is
subtracted from the other).
The split leap. I'm not a ballerina but I'm pretty sure
Yes this is true this causes day and night
Answer : The momentum of ball is, 15 kg.m/s
Explanation :
Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass of velocity of an object.
Formula of momentum is:
where,
p = momentum = ?
m = mass = 1.5 kg
v = velocity = 10 m/s
Now put all the given values in the above formula, we get:
Therefore, the momentum of ball is 15 kg.m/s
