The formula for the speeder should beV1 = d1/t1whereas the formula for the police car is d2 = vo t2 + 1/2 at2^2 where a is equal to 2.44 m/s2. when the overtaking takes place, d1 and d2 are the same, so as t1 and t2
30t = 1/2 *2.44*t2t is equal to 24.59 seconds.d then is equal to 737.70 meters
Let m = the mass of the softball.
Then the mass of the basketball is 3m.
By definition, momentum = mass * velocity.
If both the softball and basketball move at the same velocity, v, then
Momentum of the softball = mv
Momentum of the basketball = 3mv
Answer: The momentum of the basketball is 3 times that of the softball.
Answer:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies
Only units of the SI and those units recognized for use with the SI are used to express the values of quantities. Equivalent values in other units are given in parentheses following values in acceptable units only when deemed necessary for the intended audience.
Hello
This question is to be tackled using vectors. When we look at the Southwest direction, we know it lies exactly between the South and West directions, producing an angle of 45 degrees. When we take sin(45) and multiply it by the original force, we obtain the component towards West; that is:
60 * sin (45) = 42.4 Newtons
And cos(45) gives us the force towards the South direction; that is:
60 * cos(45) = 42.4 Newtons
This can also be checked by using the formula of the magnitude of a vector and squaring 42.4, adding it to the square of 42.4 and then taking the square root of the answer.
sqrt(42.4^2 + 42.4^2) = sqrt(3600) = 60
