It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the
Jaguar skidded to a stop with a constant acceleration of -3.90 m/s2 , determine the speed of the Jaguar
before it began to skid.

Step-by-step explanation:

“It was once recorded that a Jaguar left skid marks that were 290 m in length.”

Here, length means distance is 290 m.

“Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s².”

Acceleration = -3.90 m/s² (negative sign shows retardation) and final velocity is 0 m/s.

We have to find the speed of the jaguar before it began to skid. Means initial velocity.

Using the Third Equation Of Motion,

v² - u² = 2as

Substitute the known values

→ (0)² - u² = 2 × (-3.90) × 290

→ - u² = - 2262

→ u = √2262

→ u = 47.56

Therefore, the initial velocity of the or speed of the jaguar before it began to skid is 47.56 m/s.

Step-by-step explanation:

“It was once recorded that a Jaguar left skid marks that were 290 m in length.”

Here, length means distance is 290 m.

“Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s².”

Acceleration = -3.90 m/s² (negative sign shows retardation) and final velocity is 0 m/s.

We have to find the speed of the jaguar before it began to skid. Means initial velocity.

Using the Third Equation Of Motion,

  • v² - u² = 2as

Substitute the known values

→ (0)² - u² = 2 × (-3.90) × 290

→ - u² = - 2262

→ u = √2262

→ u = 47.56

Therefore, the initial velocity of the or speed of the jaguar before it began to skid is 47.56 m/s.
