The dimensional formula for kinetic energy is:
M2 L2 T2
M L2 T-2
M2 L T-2
M L2 T
Hooke’s law states that the force, F, in a spring extended by a length x is given by F = −kx. From Newton’s second law F = ma, where m is the mass and a is the acceleration, calculate the dimension of the spring constant k.

Scalar product
‘The magnitude of A multiplied by the component of B parallel to A’.
This statement is referring to
dot product
cross product
Cross product is also known as Vector product. Choose the right answer that best described the diagram above.
The magnitude of B multiplied by the component of A perpendicular to B
The magnitude of A multiplied by the to component of B parallel A
Resolve the vector to its horizontal component
x=14 sin 55
x=14 cos 55
x=55 cos 14
x=55 sin 14
