can I answer it like -10km/h? because my first answer is -10km/h, I arrived at this conclusion by firstly, listing all that I knew which is, a=? vf=0 vi=100kmh t=10sec, and used the standard formula for solving acceleration.

To find the acceleration, we need to use the formula for acceleration which is: a = Δv / Δt where: a is acceleration, Δv is the change in velocity, and Δt is the change in time. Step 1: Find the change in velocity (Δv) The change in velocity is the final velocity minus the initial velocity. In this case, the final velocity is 10 m/s and the initial velocity is 25 m/s. So, Δv = vf - vi = 10 m/s - 25 m/s = -15 m/s The negative sign indicates that the velocity is decreasing. Step 2: Find the change in time (Δt) The change in time is given as 5 seconds. Step 3: Substitute Δv and Δt into the acceleration formula a = Δv / Δt = -15 m/s / 5 s = -3 m/s² So, the acceleration of the particle is -3 m/s². The negative sign indicates that the acceleration is directed downwards, opposite to the direction of motion. ####

The formula for distance traveled is 𝑑=𝑣𝑡d=vt. Solve the formula for the velocity v.

The velocity of a particle is given by the equationv = 9t2 i + t3 j + (0.75t + 3) k m/swhere t is in seconds. Determine the following:(a) the magnitude of the particle’s acceleration when t=1.75 seconds, a = Answer m/s2.(b) the magnitude of the particle's displacement when t=1.75 seconds (r=0 when t=0), r = Answer metres.

If a car is traveling forward at 15 m/s, how fast will it be going in 1.2 seconds if the acceleration is -10 m/s^2?
