a body of mass 5kg starts and roll down 32m of aninclined plane in 4sec,find the force acting on the body

answered-by-expert Expert Answer
Initial velocity u=o, because the body was released
distance travelled= 32m
time=4 seconds
s equals u t plus 1 half a t squared 32 equals 0 cross times 4 plus 1 half cross times a cross times 4 squared a equals 4 m s to the power of negative 2 end exponent F o r c e space a c t i n g space a l o n g space t h e space i n c l i n e d space p l a n e equals m a F equals 5 cross times 4 equals 20 N

Questions 23-25 are based on the information given below. Read the information and answer the questions that follow:A bob of mass ‘m’ is suspended by a string, g be the acceleration due to gravity the bob.When the bob is stationary, the tension ‘T’ in the string is T=mg.When the bob is pulled up with an acceleration ‘a’ the tension in the string is given by T= m (g + a)When the bob is allowed to move down with an acceleration ‘a’, the tension T in the string is given byT= m (g –a)
