A car is moving along a straight horizontal road, with a constant acceleration. The car passes point A, with a speed of ums(-1). 10 seconds later, passes point B, with a speed of 45 ms(-1). The distance from A to B is 300m. Find u.

Here, we must consider our UVAST equations of motion, and our variables.

U=?ms^(-1), V=45ms^(-1) , A=?ms^(-2), S= 300m, T=10s

Our equations of motion are:

How much work must be done on a 4.0kg frictionless trolley, to accelerate it from rest to a velocity of 5.0m/s?

It must firstly be noted that, in general, the work done on an object is equal to its gain in energy.The trolley has gained kinetic energy. This can be calculated using the formula: "KE = (1/2)mv^2&q...

How would I resolve forces on a slope?

First pick a set of axis to use. This would be in the directions of which the majority of the forces follow. With the forces which are at angles to the majority of the forces, create a triangle of the ...

What is centripetal force?

For an object moving in a circular path, the centripetal force is any force which acts towards the centre of this circular path. This means it acts perpendicular to the direction of forward motion.
