Question

### Description

During operation, the jackhammer strikes the concrete surface with a force indicated in the accompanying graph. To achieve this, a 2.2-kg spike \( S \) is fired into the surface at a speed of 90 m/s.

### Graph Explanation

The figure includes a graph plotting force \( (F) \) against time \( (t) \). The graph is shaped like a triangle, starting at \( t = 0 \, \text{ms} \) and peaking at \( t = 0.1 \, \text{ms} \) with a force of 1500 kN, then decreasing back to 0 kN at \( t = 0.4 \, \text{ms} \).

### Problem Statement

**Part A**:
Determine the speed of the spike just after rebounding.

**Instructions**:
Express your answer to three significant figures and include the appropriate units.

**Input Fields**:
- \( v = \text{Value} \)
- Units
