Help with physics worksheet please! Thank you! 5. Your dog is +32 m from you. He runs straight toward you for 4.2 s, ending -3.0 m behind you. Calculate the dog's velocity.6. While on a drive, you travel the first 2.5 km at 20 m/s. For the next 1.5 km, you travel at 30 m/s. The final 4.2 km you drive at 25 m/s. How long will this entire journey take? (Hint - split this intothree constant-velocity pieces.)7. While driving with a velocity of +30 m/s, you hit the brakes for 4.2 s, after which your new velocity is 22 m/s. Calculate the acceleration you experienced while braking.8. A jogger is running at 2.0 m/s in the +x direction. When she is 85 m from you she accelerates at+0.6 m/s/s for 3 seconds. How far is she from you at the end of those 3 seconds?
