In getting ready to slam-dunk the ball, a basketball player starts from rest and sprints to a speed of 6.0 m/s in 1.5 s.

acceleration is constant. therefore, change in velocity/change in time = acceleration.acceleration = 4m/s^2now you need the equations of motion.one of them iss = ut + 1/2*a*t^2wheres= displacement (distance)u = initial velocity (initial speed)a = accelerationt = time.just plug the numbers in…s = 0*1.5 + 1/2*4*1.5^2= 4.5m...

The equation you’re looking for is one of the equations of motion:s = (v + u)t / 2u = 0m/s (initial speed) v = 1.5m/s t = 1.5s s = ?m (distance)s = (6 + 0) x 1.5 / 2 = 4.5 metresThe equation basically says that the distance is equal to the average speed [(v+u)/2] multiplied by the time taken....

S=0.5(U+V)tS = the distance U = the initial velocity V = the final velocity t = time S = 0.5 x (0+6.0) x 1.5 = 4.5 meters simples... Show More

a million) stable questions. 2)uncertain how they began shifting yet they stay close to the nucleus with the aid of electric powered forces no longer magnetic. threat is that there small mass and non-0 value cause them to very in probability of stream. 3)easy is an constantly changing mix of electric powered and magnetic fields. to ask what easy is is looking what electric powered and magnetic fields are. the sphere isn’t capacity in spite of the indisputable fact that it includes capacity. subsequently, easy isn’t capacity in spite of the indisputable fact that it possises capacity. 4) You working doesnt particularly create capacity. Chemical reactions create the capacity. that’s then tranfered and make the main of with the aid of your physique. 5) capacity required to maintain electrons in orbit is in all threat via in general a play between potential capacity and quatum mechanical consequences. 6)easy would not take in area. easy isn’t remember. capacity isn’t atoms shifting. capacity is something that has the capacity to accomplish paintings. paintings is while a rigidity is utilized over a distance. the place capacity got here from in general is a secret. It cant be defined what occurred until eventually now the massive bang (in case you suspect that ) Thamks... Show More
