Answer Text

Answer :

distance travelled =96 cm

Solution :

Given Initial velocity motorboat, u = 0 <br> Acceleration of motorboat, a = 3.0 m `s^(-2)` <br> Time under consideration, t = 8.0 s <br> We know that Distance, s = ut + (1/2) `at^(2)` <br> Therefore, The distance travel by motorboat = `0xx8+(1//2)3.0xx8^(2)` <br> = `(1//2)xx3xx8xx8` m <br> = 96 m

A football player, starting from rest at the line of scrimmage, accelerates along a straight line for a time of 1.5 s. Then , during a negligible amount of time, he changes the magnitude of his acceleration to a value of `1.1 m//s^(2)`. With this acceleration, he continues in the same direction for another 1.2s, until he reaches a speed of 3.4 m/s. What is the value of his acceleration ( assumed to be constant ) during the initial 1.5 s period ?

A car starts moving on a straight road. It makes the entire journey in three parts. The total time of journey is 25 s. For first part it accelerates at a constant rate `5m//s^(2)`. For second part it moves with a constant speed. For the third part it retards at constant rate `5m//s^(2)` to come to rest. <br> If the average speed for entire journey is 20 m/s, time period of first part of journey is
