A cyclist travelling along a straight level road accelerates at 1.2 m/s2 for 5 seconds. The mass of the cyclist and the bicycle is 80 kg
(a)
calculate the resultant force needed to produce this acceleration
Show clearly how you work out your answer and give the unit.
Resultant force =

thermal energy is the answer

no sign of dia of fuel cell

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
