If a man pulls a box with a force of 90 N at an angle of 45 degrees, then what are the X and Y components of the force?
X = 0 N, Y = 45 N
X = 1 N, Y = 45 N
X = 64 N, Y = 64 N
X = 90 N, Y = 45 N
Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

The rate of change of momentum is known as?
force
impulse
inertia
acceleration
What is the product of mass and velocity known as?
acceleration
momentum
impulse

Rutherford has a mass of 15kg. What is his weight on Earth? - in N.
146N
147N
148N
149N
v=u+at
final velocity = initial velocity + (acceleration x time)
initial velocity = final velocity + (acceleration x time)
displacement = change in velocity + (acceleration x time)
change in velocity = displacement + (acceleration x time)
A city block happens to be a square of side 800m. A cycling courier spots a cat at one corner of the block and does a full lap in an attempt to run it over. The lap takes 3 min 20 secs. What is the cat's average speed, in m/s?
16m/s
17m/s
26m/s
27m/s
