6) An object falls a distance h from rest. If it travels 0.50h in the last 1.00 s, find (a) the time and (b) the height of its fall. (c) Explain the physically unacceptable solution of the quadratic equation in that you obtain.

A vehicle collides with an immoveable concrete embankment. Estimate the number of 'gs' the occupant experiences when the front end of the vehicle collapses 0.93 m when bringing the vehicle to rest from a speed of 85 km/hr. Assume uniform (constant) deceleration. Ref. 2.11 Express algebraic solution in terms of ds, vo and g. As 0.93 VO 85

Please don't provide handwritten solution...

A 5kg collar is suspended by a spring at rest a Point A, as shown. The unstretched lenght of the spring is 4m. If the collar is pulled down to Point B and then is released from rest, what is speed of collar when it has moved up 1m?

Hello. Answer is s=5.76m (how far the car travels when the driver slams brake on an inclined surface). I am uploading this question as the example answer's working out was so horrific I cannot follow through. I would like to see working out how the calculations equate to the answer being s=5.76m.    Many thanks

An ice hockey player of mass m1 = 93.5 kg hits a puck of mass m2 = 0.14 kg, giving the puck a speed of v = 39.5 m/s. a) If both are initially at rest and if the ice is frictionless, how far, in terms of the variables in the problem, does the player recoil in the time it takes the puck to reach the goal, a distance d away?  b)If both are initially at rest and if the ice is frictionless, how far, in centimeters, does the player recoil in the time it takes the puck to reach the goal, 15 m away?

If friction is ignored, the time t (in seconds) required for a block to slide down an inclined plane (see the figure) is given by the formula t= 2a gsin@cos 8 where a is the length (in feet) of the base and g 32 feet per second per second is the acceleration due to gravity. How long does it take a block to slide down an inclined plane with base a 80 feet when 0-60? (Do not feet seconds feet per second Then round to two decimal places as needed.), MUS

I need solution for all the calculation questions on the image

Please and thank

An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sees the car, the locomotive is 330 m from the crossing and its speed is 21 m/s. If the engineer's reaction time is 0.44 s. what should be the magnitude of the mini- mum deceleration to avoid an accident? Answer in units of m/s2.
