Answer:
d. N*m
Explanation:
Workdone which is measured in Joules is calculated using the formula;
Workdone = force * distance
Where;
Force is measured in Newton
Distance is measured in meters.
Therefore, workdone also has the measurement of Newton-meters.

Answer:
22km/h
Explanation:
The speed of the keys relative to the ground will be given by the sum of speed of keys with respect to the ground and the speed of keys with respect to the skater
Given that the speed of keys with respect to the ground is 8 m/s while the speed of keys with respect to skater is 14 km/h then the relative speed which combines both speeds will be 8+14=22 km/hr
V1 * sin(θ) where θ is the angle v1 makes with the vertical.
