Answer:
6.8 m/s2
Explanation:
Let g = 9.8 m/s2. The total weight of both the rope and the mouse-robot is
W = Mg + mg = 1*9.8 + 2*9.8 = 29.4 N
For the rope to fails, the robot must act a force on the rope with an additional magnitude of 43 - 29.4 = 13.6 N. This force is generated by the robot itself when it's pulling itself up at an acceleration of
a = F/m = 13.6 / 2 = 6.8 m/s2
So the minimum magnitude of the acceleration would be 6.8 m/s2 for the rope to fail
Speed = 52/1.57576= 33 m/s
Explanation:
Distance = speed * time
Given , the distance traveled by the baseball = 52 m
Speed of sound in air = 330 m/s
Total time = 1.73333 s .
Total time for the student to hear the sound of the gong is the sum of the time take for the baseball to reach the gong and the time taken by the sound to travel back.
Distance traveled by the sound is 52 m and the speed is 330 m/s
So time taken by the sound to travel back = distance traveled / the speed
=> time = 52/330 s = 0.15757 s
Time taken by the base ball to reach the gong is the total time - the time taken by the sound
=> time taken by base ball = 1.73333 - 0.15757 = 1.57576s
Speed of the base ball to reach the gong = distance / time
Speed = 52/1.57576= 33 m/s
velocity is magnitude and direction. its unit is meter per second
