John pushes his brother danny on a skateboard. john applies a force of 29 n and danny's acceleration is 0.4 m/s

The combined mass of Danny and his skateboard = m = 72.5 kg

Explanation:

Force applied by john = F = 29N  

Danny’s Acceleration = a = 0.4 m/s  

Combined mass of Danny and his skateboard = m = ?

According to Newton’s second law of motion:

                                   F = ma  

                                  m = F/a  

                                  m = 29/0.4

                                  m = 72.5 kg

Hence, the combined mass of Danny and his skateboard will be 72.5 Kg.

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

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
