Hi I have been given the position vector of a particle, and have then differentiated this to get the velocity vector for the patricle. I have now been asked to find the speed, but am...

If a bowling ball is dropped out of an airplane, what will it's speed (velocity) be after 3.4 seconds, assuming no air resistance? (Hint: Use the equation v = 32t

I'm not sure how to approach this problem and I'd really appreciate any help! If a ball is thrown directly upward with a velocity of 36 ft/s, its height (in feet) after t seconds is given...

An airplane is flying at 200 m/s at an angle of 30o north of east. How fast is the plane flying North? An airplane is flying at 200 m/s at an angle of 30o north of east. How fast is the plane flying...

It is a velocity question

What is the momentum of a system of two particles with these respective masses and velocities: 3.75 kg moving north at 5.6m/s and 4.2 kg moving northwest at 2.3m/s?

A 42 kg child slides from the top of a 3 m high playground slide. With what speed will the child reach the bottom of the slide assuming: (a)There is no friction? (b) 23 J of energy is dissipated due...

Options are i) v=0 ii) v=2u iii) v=0.5u iv) v=u

A ball is thrown upward with an initial velocity of 42 meters per second from a cliff that is 10 meters high. The height of the ball is given by the quadratic equation h=-4.9t^2+ 42t+70 where...

A particle of mass m = 10kg moves along a straight line under the action of force F = λ/x4 , where λ is some constant. A measurement shows that the particle passes the point x = 1m with...
