Steven carefully places a ????=1.95 kgm wooden block ~ above a frictionless ramp so the the block begins to slide down the ramp from

The forces that do non-zero occupational on the block space gravity and also normal reaction force


In this inquiry we have actually given,

mass of the wooden block,


angle between ramp and horizontal surface,


in this instance ramp is friction less so friction pressure will be zero and hence work-related done as result of friction pressure will it is in zero.

As wooden block is slide down because of gravity(gravity is pulling the block in bottom direction).

so two forces will plot on wooden block as it slides down the ramp that space gravity and also normal reaction force.

Therefore, the pressures that do non-zero job-related on the block are gravity and also normal reaction force.

A car is travel at a rate of 30 m/s. The decelerates at a price of 12 m/s^2. Calculate the time taken for the auto to concerned
user100 <1>

The come your question is: t = 2.5 s



vo = 30 m/s

a = -12 m/s2

t = ?

vf = 0 m/s


vf = vo + at


0 m/s = 30 + (-12)t

Solve it because that t -30 = -12t

t = -30 / -12

t = 30/12 = 15/6 = 5/2

t = 2.5 s
